Answer :
Final answer:
Ohm's Law relates the potential difference across a resistor to the current passing through it. The resistance of a resistor can be calculated using the formula R = V/I. In the specific circuit provided, a potential difference of 114 volts exists.
Explanation:
Ohm's Law states that the potential difference (voltage) across a resistor is directly proportional to the current passing through it and the resistance of the resistor.
To calculate the resistance of a resistor, the formula R = V/I is used, where R is the resistance in ohms, V is the potential difference in volts, and I is the current in amperes.
In the given circuit with a current of 3 amperes and a resistance of 38 ohms, the potential difference can be found by multiplying the current with the resistance (V = I * R), resulting in a potential difference of 114 volts across the circuit.
