Question

What would be the Q factor for a purely inductive circuit?

• A. $1$
• B. $0$
• C. $2$
• D. $\infty$

Answer 1

The correct option is D $\infty$

Capacitance of purely inductive circuit is zero i.e. $C=0F$

Q factor $Q=\frac{1}{R}\sqrt{\frac{L}{C}}$

$Q=\frac{1}{R}\sqrt{\frac{L}{0}}=\infty$
