If the total voltage in a circuit is 233 volts and the impedance is 58.3 Ohm, what is the current?

To determine the current in a circuit with a total voltage of 233 volts and an impedance of 58.3 Ohms, you can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by impedance (Z). The formula is:

I = V / Z

Substituting the given values into this formula:

I = 233 V / 58.3 Ω

When you perform the calculation, it results in approximately 4 Amps. This matches the choice indicating 4 Amps, confirming that this value indeed reflects the current flowing through the circuit based on the provided voltage and impedance. Understanding Ohm's Law is fundamental for linemen, as it allows them to quickly calculate current in AC and DC circuits, facilitating correct installations and maintenance.
