## What is the current in a circuit with an applied voltage of 120 volts and a resistance of 80 ohms?

1.5 amperes

Calculate Amps For a circuit with an applied voltage of 120 volts across a resistance of 80 ohms: Current(I) = 120 volts divided by 80 ohms. Current = 1.5 amperes.

### How do you find power with resistance and voltage?

Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

#### What is the current through a 100 ohm resistor?

Yes value of resistance is 100 ohm and it can handle 5 watt power or it can carry current up to √(5/100) (from P= i^2 R or i = √(P/R)) or 0.223 amp or 223 mA.

**What is the current flowing through an electric circuit if it has 120 volts and 10 ohms of resistance?**

12 amps

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 do you calculate resistance in a circuit?**

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

## What is the resistance of the circuit with a 100 V source and 10 A current?

Answer: The resistance of the circuit is 2 ohm.

### How do you calculate the voltage across a resistor?

You take the basic formula of E = I x R, solve for R -> R = E / I. In other words, take the required voltage drop (in volts) and divide by the current (in amps) in the resistor and determine the resistance (R) in ohms.
