Frequently asked questions
- What units are used?
- Volts (V) for voltage, Amperes (A) for current, Ohms (Ω) for resistance, and Watts (W) for power. Keep units consistent.
- Does Ohm's Law apply to AC circuits?
- For pure resistors, yes. For capacitors and inductors you need impedance Z (complex resistance), and V = IZ replaces V = IR.
