Question 1

How do you convert power to current?

Accepted Answer

I = P ÷ V for DC. For AC, I = P ÷ (V × PF). A 60W bulb at 120V draws 0.5A (ignoring PF).

Question 2

Why convert between power and current?

Accepted Answer

Wire sizing requires current (amps). Electricity billing uses power (kWh). Both are essential.

Question 3

What's the relationship between volts, amps, and watts?

Accepted Answer

Power (Watts) = Voltage (Volts) × Current (Amps). To find any value, divide or multiply: Amps = Watts/Volts, Volts = Watts/Amps.

Question 4

Is AWG or metric wire gauge better?

Accepted Answer

AWG (American Wire Gauge) uses arbitrary numbers where smaller = thicker. Metric (mm²) directly indicates cross-sectional area, making calculations easier.
