If C,R,L and I denote capacity, resistance, inductance and electric current respectively, the quantities having the same dimensions of time are

\left( 1 \right)\,CR,\,\,\left( 2 \right)\,\frac{L}{R}\,,\,\,\left( 3 \right)\,\sqrt {LC} \,\,\left( 4 \right)\,L{I^2}

View answer and explanation

Correct option: D

(1), (2) and (3) only

Option D ((1), (2) and (3) only) is correct because CR, L/R, and √(LC) all have the dimensions of time.
