Your alternator/generator can handle up to a 30 amp load at 12 volts. Milliamps is short for milliamperes and amps is short for amperes. The LED's Operating Voltage is 2.0 Volts (if you had more then one just add up each voltage, so 3 LED's would use 6 volts) The LED's Operating Current is 20ma (Milliamps) or 0.02 Amps We need to find out 2 things, one the Resistance value needed to drop 12 Volts to 2 Volts and the second part of the problem is the wattage rating of the resistor. Convert 3 millivolts to volts: How to convert Milliamperes to Watts Per Volts (mA to W/V)? Milliamps is short for milliamperes and amps is short for amperes. Dividing 300 milliwatts by 3 volts indicates the circuit board requires a current of 100 milliamps … If your control circuit is using a 250Ω resistor: mA: Amps x Resistance: Volts: 4: The black lead goes to the "COM" jack; the red lead goes to the "+" or plus jack -- unless the meter has a milliamps jack. Calibration procedures can be pre-defined and used for calibrations on site. The Volts are important and generally the power required by your device. The current I (A) in amps is equal to the current I (mA) in milliamps divided by 1000 milliamps per amp:. 300 milliamps is only .3 amp. At 120 volts, 300 Watts = 2.5 Amps. Definition: In relation to the base unit of [electric current] => (amperes), 1 Milliamperes (mA) is equal to 0.001 amperes, while 1 Watts Per Volts (W/V) = 1 amperes. Therefore amps are equal to milliamps divided by 1000 milliamps per amp: Enter the numbers and then click 'calculate'. In that case, connect to that rather than the "+" jack. Convert current of 300 milliamps to amps: The current I in amps (A) is equal to 300 milliamps (mA) divided by 1000mA/A: I (A) = 300mA / 1000mA/A = 0.3A . Switch off the power to the circuit. 140/360 = .389 amps (or 389 milliamps) A 300-milliwatt circuit board is connected to a 3-volt power supply. Many multimeters have an mA (milliamp) port, which in some cases is combined with the voltage and ohm port, and also have a 10 A or 20 A port for higher current. V (V) = I (A) x R (Ω), which means that the voltage in volts (V) is calculated by multiplying the current in amps with the Resistance in Ohms (Ω). How to convert Milliamps to Amps: 1 mA = 0.001 A. or. 1 mV = 10-3 V = 0.001 V. Millivolts to volts formula. Example. A current of 0.1 ampere for a mere 2 seconds can be fatal. "At currents as low as 60 to 100 milliamperes, low-voltage (110-220 volts), 60-hertz alternating current traveling through the chest for a split second can cause life-threatening irregular heart rhythms. It is … Calculate Power, Current, Voltage or Resistance. Here is the answer to the question:5/8 as percent or how to convert 5/8 to percent. Safety depends on the fusing or breaker. Primary: 120 volts 50/60 Hz Primary also has 21V RMS @ 150mA Secondary: 1400 volts … This is a very rare AC adapter, actually goes down to the 1.5 volts. Calculate voltage, current, resistance, and power. Calculators for Ohms Law. Convert watts, volts, and amps. Our conversions provide a quick and easy way to convert between Power or Electricity units. email: suggestionsfeed@gmail.com Formula is (mAh)*(V)/1000 = (Wh). First select the two known quantities. Extended Keyboard; Upload; Examples; Random Philip M. 7 years ago. This online calculator was designed with a program that can execute any conversions related to amps and watts or ohms being converted to volts. An unfused 30mA supply may cause a fire if it is loaded/shorted to, say 300mA, while a 1 Amp supply can operate safely at that current. Online calculator to convert amps to milliamps (A to mA) with formulas, examples, and tables. I (A) =1000 x S (VA) / (√3 x V L-L (V)) = S (VA) / (3 x V L-N (V)), which means that the current in amps is calculated by multiplying 1000 by the apparent power in volt-amps. The electronic pressure calibrator LR-Cal LPC 300 measures pressure, volts and milliamps and supplies 24 VDC as source for transmitter. The current I in amps (A) is equal to the voltage V in volts (V), divided by the resistance R in ohms (Ω). About 300-500 milliamperes of direct current is needed to have the same effect." 1 A = 1000 mA. Wheeler 90000 Lighting Coil 40000 Volts 300 Milliamps Brass Terminals in Coils. Love it and a pleasant surprise too. Example. Next, click on the appropriate units which are 'volts' and 'milliamps'. 1 x 0.001 W/V = 0.001 Watts Per Volts.

Volts, Amps, Watts & Ohms Calculator. Top of page claims device goes down to 3 volts , then half way down the page it claims to go down to 1.5 volts. A = mA / 1000. At 100 volts, 300 Watts = 3 Amps. 300 milliamps at 110 volts. Purchasing Info. Got feedback? Use this milliamps to microamps ( milliampere to microampere ) converter to convert electric current values from mA to µA, where 1 milliampere is equal to 1000 microampere. Refer chart and conversion calculation formula. Output Power (Watts): 16.8 The result is the divided by the square root of three multiplied by the line to line voltage in volts. In control circuits, the most common resistor values are 250Ω & 500Ω, although any value can be used depending upon the device. At 240 volts, 300 Watts = 1.25 Amps. For example, if you have a 3000 mAh battery that runs at 5 Volts and 15 Watts, then the time that the battery will last for is (3000*5)/(15*1000) = 1 Hours. The adaptor can only give out 19volts but your device requires 29 volts. How to convert amps to milliamps You can calculate other resistance values with the following formula: R = (Vs - Vz) / Imax Where R is the resistance in ohms, Vs is the unregulated source voltage, Vz is the Zener’s voltage and Imax is the maximum current you want. Time is also a factor. At 10 volts, 300 Watts = 30 Amps. Ohms to Amps calculation with watts. As Voltage = Current x Resistance the current depends on body resistance. I figured I didnt see one so heres a small list I started.This will help you get most out of the isolated outputs of a Voodoo Lab PP2+ and even a one spot which is 1700 mA. V (V) = V (mV) / 1000. Enter the power in watts (W), resistance in ohms (Ω), then press the Calculate button to get the result in amps (A). The radio will only draw as many amps as it needs (in this case, 300mA), so you can just connect it up without problems. The resistor was calculated to work with a 24V source, a 12V output, and 300 milliamps of current. What is the resistance? Dividing 140 watts by 360 volts shows a current of 389 milliamps running through it. 8 to 16 Volts 500 Milliamps 8 Watt AC to DC Switching Enclosed LED Power Supply 8 to 16 Volts @ 500 Milliamps Specifications. It would require about 30mA*10KOhms=300 Volts to cause a body current of 30mA. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. If you’re reading a low current in milliamps – below the number of milliamps listed beside the port, often 200 mA – insert the red lead into the port labeled “mA.”
