Question

What if current source and voltage source are interchanged in rc circuit questions?

Answer 1

Explanation:

In an RC circuit connected to a DC voltage source, voltage on the capacitor is initially zero and rises rapidly at first since the initial current is a maximum: V(t)=emf(1−et/RC) V ( t ) = emf ( 1 − e t / RC ) . The time constant τ for an RC circuit is defined to be
