Question 1 of 7
Explain the relationship between power, voltage, and current for a resistive single-phase load, referencing the provided calculation.
Strong Interview Answer
The electrician should calculate current by dividing the power (4,800 W) by the voltage (240 V) as per the fundamental relationship in electrical circuits. This directly yields the current, demonstrating a clear understanding of power and voltage's influence on current flow.
What to Listen For
- Power divided by voltage
- current calculation
- phase configuration
- unit identification
Caution
Listen for an explanation of the power-voltage-current relationship, not just a restatement of the formula.
