A rectangular pulse of duration T and magnitude A has the Laplace transform
The time constant of the circuit shown below is
Assertion (A): Laplace transform is preferred for solving networks involving higher order differential equations.
Reason (R): The classical method for solving differential equations of higher order is quite cumbersome.
Assertion (A): In a purely capacitive circuit, the current wave is more distorted than the voltage wave.
Reason (R): The harmonics in the current wave are increased in proportion to their frequency numbers.
The time constant of the circuit shown below is
