What is the current in a 120V circuit of the resistance is 20?

The current in a resistance of 20 ohms and 120 V circuit is 6 Ampere.

What is the current in a 120V circuit if the resistance is 4ω?

The total circuit current is: I=E/R, or 120V/120Ω, or 1 Amp. Now, the voltage across the 80,120 and 240 ohm resistors (40 ohm equivalent) is E=IxR, or 1 Amp x 40Ω, or 40 Volts. And finally, the current through the 120 ohm resistor can be calculated by: I=E/R, or 40 Volts/120Ω, or 1/3 Amp.

What is the current when the voltage is 120V and the resistance is 10 ohms?

12 amps
Using Ohm’s Law to Calculate Current Q: If a 120-volt voltage source is connected to a wire with 10 ohms of resistance, how much current is flowing through the wire? A: Substitute these values into the equation for current: Current = 120volts10ohms = 12 amps.

How much current does a 100w lamp draw when connected to 120v?

A 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps. Plz mark as BRAINLIEST.

How do you find current with resistance and power?

Ohms Law and Power

To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

What happens to the current in a circuit as the resistance increases?

Ohm’s law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed.

What is the resistance in a lightbulb with a voltage of 25 V and a current of 0.2 A?

The resistance for the lightbulb is 125 Ω.
