Question 1

What is circular mils?

Accepted Answer

Area measurement for round wire: diameter in mils squared. 1 cmil = (1 mil)² = area of wire with 1 mil diameter.

Question 2

How do you convert AWG to circular mils?

Accepted Answer

Formula: cmil = 10^((36-AWG)/10) × 1974. Example: 10 AWG = 10,380 cmil.

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.
