Question 1

What is a siemens?

Accepted Answer

Unit of conductance, inverse of ohms. 1 S = 1/Ω. Higher siemens means lower resistance.

Question 2

How do you convert siemens to ohms?

Accepted Answer

R = 1/G. Example: 0.02 S = 1/0.02 = 50 Ω. Conductance is reciprocal of resistance.

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.
