Question

Assertion $\left(A\right)$: $\text{KVL}$ rule can also be applied to an a.c. circuits.

Reason $\left(R\right)$: Varying electrostatic field is non-conservative

• A. Both $\left(A\right)$ and $\left(R\right)$ are true, and $\left(R\right)$ is the correct explanation of $\left(A\right)$
• B. Both $\left(A\right)$ and $\left(R\right)$ are true, but $\left(R\right)$ is not the correct explanation of $\left(A\right)$
• C. $\left(A\right)$ is true but $\left(R\right)$ is false
• D. $\left(A\right)$ is false but $\left(R\right)$ is true

Answer 1

The correct option is C $\left(A\right)$ is true but $\left(R\right)$ is false

(i). $\text{KVL}$ can be applied for circuits, it can be a.c. (or) d.c. circuit. Basically $\text{KVL}$ is energy conservation.

(ii). Varying electrostatic field can be conservative. But electrostatic field induced by the time varying magnetic field is non - conservative.
