Question 1

How does a transformer work?

Accepted Answer

Changes voltage via electromagnetic induction. V₂/V₁ = N₂/N₁ (turns ratio). Power stays constant (minus losses).

Question 2

How do you calculate transformer output?

Accepted Answer

V_out = V_in × (N_secondary/N_primary). A 120V input with 2:1 ratio gives 60V output.

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.
