How many amps in 12v 150w?
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
How much amps take 12v 50w halogen lamb?
To calculate the current, you can use the formula: current (in amps) = power (in watts) / voltage (in volts). So, for a 50W halogen lamp operating at 12V, the current draw would be approximately 4.17 amps (50W / 12V = 4.17A).
12v DC 18va how many amps amps?
12 V DC, 18 VA (watts) how many amps? Formula: amperage I = power P (VA) divided by voltage V. So, amperage I = 18 watts / 12 volts = 0.083 amperes.
How many amps in a 50 watt 12v light?
Amps = Watts/Volts55/12= 4.583333
What is the resistance of a 12v lamp in a 12v circuit?
The formula you are looking for is W = I x E.
How many amps in 12v 150w?
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
Determine the power dissipated if the voltage supplied to a circuit is 12V and the current measured is 3A?
The power dissipated by a circuit with a voltage of 12V and a current of 3A is 36W. Watts is Volts times Amps.
What will be the amps of a 12v 2amp circuit if there is a 12ohm resistor on it?
The formula you are looking for is I = E/R. Amps = Volts/Resistance. If you say it is normally a 2 Amp circuit, it normally draws 2 amps. Therefore the original resistance offered to the 12v battery is 2/12 = 6 Ohms. If you then connect a 12 Ohm resistor in series, they are added, so R = 18 Ohms. Now if you put 12v across this circuit it will draw 12/18 = 0.66 Amps. Or If you just put a 12 Ohm resistor across the 12v supply it will draw 1 Amp. If the circuit is protected by a 2 Amp fuse, it will not blow, but the resistor will get hot.
How many amps at 12 volts equals 16 amps at 120 volts?
160 amps at 12v.
How many amps at 120 volts equals 16 amps at 12 volts?
160 amps at 12v.
Can I use a 12v 18 amp battery and connect to a circuit that asks for 12v Static current 6mA Can I use resistors to lower the amps on the 12v 18amp battery or can I just connect it up?
Just connect the circuit. It will only draw the amps it needs to operate. It is just like connecting a 100 watt light bulb that draws way less than 1 amp, to a 20 amp household circuit.
How many amps do 12v 25w light use?
well the equation for amps is a= watts/volts so 25/12= 2.0833333333amps
What capacitor or circuit will keep a 12V device running at 3 amps for 30 seconds after it is turned off?
The easiest way is to connect a 12v battery to the circuit. Be sure to place a diode in the positive line (watch polarity) to keep the battery from loading down the power supply when charging.
How is twelve volts at five amps converted into milliamps?
12V 5A = 12V 5000mA
How much amps take 12v 50w halogen lamb?
To calculate the current, you can use the formula: current (in amps) = power (in watts) / voltage (in volts). So, for a 50W halogen lamp operating at 12V, the current draw would be approximately 4.17 amps (50W / 12V = 4.17A).
What draw in amps is a standard brake light?
About 0.6 amps for a 12v 21w bulb
To run 12v dc things in a car the battery outputs 12v regularly but it can go as high as 14.4 when the engine is running I need a circuit to regulate this at say 12v 10 amps to prevent over voltage?
the alternator is what puts out the 14.4 volts. if you wish to figure out the circuit use the formula A*R=V so you take the voltage 12 divide by the amp 12 and you get 1.2 as the resistance. so in your circuit, the max allowable load is 1.2 ohms.
