Current times resistance equals what?
That's Ohm's law. Volts = Current (or Amps) * Resistance.http://en.wikipedia.org/wiki/Ohms_law
How many volts are required to push 3 amps through a resistance of 4 ohms?
Just use Ohm's Law: V=IR (voltage = current x resistance; using units: volts = amperes x ohms).
How much current flows in a 1000 ohm resistor when 1.5 volts are impressed across it?
Ohm's Law is that Voltage Drop = Current x Resistance. So Current = Voltage Drop/Resistance. In this case Current = 1.5/1000 amps, or 1.5 milliamps
If you multiply electric current times resistance what will it be in units?
That depends on what units you use as input. If you put in current in Amps and Resistance in Ohms you will get voltage in Volts.AnswerCurrent is measured in amperes. Resistance is measured in ohms, which is a special name given to a volt per ampere. Multiply amperes by (volts per ohm), and you are left with volts.
How do you work out amps from watts and voltage?
Ohm's law states that you could calculate the current (Amp), resistance (Ohm), or voltage (Volt) as long as you know the other two. Watts is not part of this law. Therefore, your question does not give enough information.
What are electrical measurements based on?
voltage (volts) current (amps) resistance (ohms)
What is the voltage of an appliance that has a current of 3 amps and a resistance of 4 ohms?
12 volts.
How do you work out amps in an electrical circuit?
Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)
What voltage required to send a current of 4 amps through a resistance of 60ohm?
16 volts
What is the resistance of the circuit if the voltage is 230 volts and the current flowing is 5 amps?
The resistance of the circuit will be 46 ohms
What is the resistance in a simple circuit if voltage is 12 volts and current is 3 amps?
Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.
What is equal to voltage times current?
Power, in 'watts'.
What is the unit for measuring voltage?
Volts is the unit measurement for voltage Current is amperes or amps for short Resistance is ohms
How do I figure watts if I know voltage and ohms?
Volts time amps equals watts so watts divided by volts equal amps.
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
What voltage is required to sustain a current of 0.50 through a light bulb resistance of 190?
The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance
Is volts divided by amps resistance?
No. Current is voltage divided by resistance.i.e. V=IR, which means I=V/R
