Question

The quantities RC and $\left( \frac{L}{R} \right)$ ( where $R, L$ and $C$ stand for resistance, inductance and capacitance respectively ) have the dimensions of

• A. force
• B. linear momentum
• C. linear velocity
• D. time

Answer 1

Answer: (D)

time

Answer 2

$RC$ is the time constant of $RC$ circuit and $\left(\frac{L}{R}\right)$ is the time constant of $L R$ circuit. Hence, both $RC$ and $\left(\frac{L}{R}\right)$ have the dimensions of time
