If RR and LL represent respectively resistance and self inductance, which of the following combinations has the dimensions of frequency?

A

(a) RL\frac{R}{L}

A

(b) LR\frac{L}{R}

A

(c) RL\sqrt{\frac{R}{L}}

A

(d) LR\sqrt{\frac{L}{R}}

Explanation

Solution

(a)

Sol. RL=V/IV×T/I=1T=\frac{R}{L} = \frac{V/I}{V \times T/I} = \frac{1}{T} =Frequency
