Question

Q-factor can be increased by having a coil of (A) large inductance, small ohmic resistance (B) large inductance, large ohmic resistance (C) small inductance, large ohmic resistance (D) small inductance, small ohmic resistance

Q-factor is given by Q=(1/R)√(L/C) ∴ If resistance R is decreased, Q increases and inductance L is increased, Q increases.

Q. Q-factor can be increased by having a coil of

large inductance, small ohmic resistance

large inductance, large ohmic resistance

small inductance, large ohmic resistance

small inductance, small ohmic resistance

Q-factor is given by $Q = \frac{1}{R} \frac{L}{C}$
$∴$ If resistance R is decreased, Q increases and inductance L is increased, Q increases.

Q. Q-factor can be increased by having a coil of

large inductance, large ohmic resistance

small inductance, large ohmic resistance

small inductance, small ohmic resistance

Q-factor is given by Q=R1​CL​​ ∴ If resistance R is decreased, Q increases and inductance L is increased, Q increases.
