JEE MAIN - Physics (2022 - 27th June Evening Shift - No. 14)
If L, C and R are the self inductance, capacitance and resistance respectively, which of the following does not have the dimension of time?
RC
$${L \over R}$$
$$\sqrt{LC}$$
$${L \over C}$$
Explanation
$$U = {1 \over 2}L{i^2} = {1 \over 2}C{V^2}$$
So, $$\left[ {{L \over C}} \right] = {{{V^2}} \over {{i^2}}} = {R^2}$$ is not the dimension of time.
