Question

If the resistance in a 120-V circuit was 40 Ohms, what would the current be in amperes?

Answer 1

Using Ohm's law, the current in a 120-V circuit with a resistance of 40 Ohms is calculated as 3 amperes (A).

Step-by-step explanation:

If the resistance in a 120-V circuit is 40 Ohms, we can calculate the current in amperes using Ohm's law, which states that current (I) is equal to the voltage (V) divided by the resistance (R). By applying Ohm's law:

I = V/R

Substitute the given values:

I = 120 V / 40 Ω

This calculation will give us the answer:

I = 3 A

Therefore, the current in amperes would be 3 A when a resistance of 40 Ohms is present in a 120-V circuit.
