FAQs

Question: What is the time constant in an RC circuit?
Answer: The time constant (τ) in an RC circuit is the product of resistance (R) and capacitance (C), represented as τ = R × C. It indicates the time taken for the voltage across the capacitor to reach approximately 63.2% of its final value.

Question: How does electromagnetic induction occur in circuits?
Answer: Electromagnetic induction occurs when a changing magnetic field induces an electromotive force (EMF) in a conductor, leading to the generation of current. This principle is fundamental in the operation of various electrical devices.
