Question 1

How do you find AWG wire diameter?

Accepted Answer

Formula: d(inches) = 0.005 × 92^((36-AWG)/39). 10 AWG = 0.1019 in, 14 AWG = 0.0641 in.

Question 2

Does larger AWG number mean thicker wire?

Accepted Answer

No, opposite! Smaller AWG = thicker wire. 10 AWG is thicker than 14 AWG.

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.
