Question

The dimensions of $RC$, where $R$ is resistance and $C$ is capacitance are same as that of :

• A. Inverse time
• B. Time
• C. Square of time
• D. Square root of time

Answer 1

Answer: (B)

$\mathrm{RC}=\left(\frac{\mathrm{V}}{\mathrm{I}}\right)\left(\frac{\mathrm{q}}{\mathrm{V}}\right)=\frac{\mathrm{q}}{\mathrm{I}}=\frac{\mathrm{I}\times \mathrm{t}}{\mathrm{I}}=\mathrm{t}$
