How do you test a circuit?

Answer
To test a circuit: First, disconnect power for safety. Use a multimeter to check resistance (ohms) to verify connections and component values. Then apply power and measure voltage across components and current through the circuit. Compare readings to expected values using Ohm's Law. Look for opens (infinite resistance), shorts (zero resistance where there shouldn't be), or incorrect values.
