1 Answer
The time constant \( \tau \) of an RL series circuit is given by the formula:
\[
\tau = \frac{L}{R}
\]
Where:
MCQ Example:
What is the time constant of an RL series circuit?
A) \( \frac{R}{L} \)
B) \( \frac{L}{R} \)
C) \( L \times R \)
D) \( R \times L \)
Correct Answer: B) \( \frac{L}{R} \)
\[
\tau = \frac{L}{R}
\]
Where:
- \( \tau \) is the time constant (in seconds),
- \( L \) is the inductance of the coil (in Henrys),
- \( R \) is the resistance of the resistor (in Ohms).
