The q of a coil is independent of frequency
WebbOn what factors does the self-inductance of a coil depend? Solution According to Faraday's law, when the current changes with time in a circuit an emf is induced. This induced emf is directly proportional to the change in magnetic flux linked with the circuit with respect to time.
