Question

when an automobile battery with an emf of 12.6 v is connected to a resistor of resistance 25.0 ω , the current in the circuit is 0.480 a . find the potential difference across the resistor.

Answer 1

The potential difference across the resistor is 12 volts.

Step-by-step explanation:

The potential difference across the resistor can be found using Ohm's Law, which states that V = IR, where V is the potential difference, I is the current, and R is the resistance. In this case, the current is given as 0.480 A and the resistance is 25.0 Ω. Substituting these values into the formula, we get V = (0.480 A)(25.0 Ω) = 12 V. Therefore, the potential difference across the resistor is 12 volts.
