Explanation Calculation: Refer to Figure in the respective question. Redraw the Figure as shown in Figure 1 for t < 0 . By using voltage division rule, write the expression for V o . V o = 60 V ( 25 k Ω 25 k Ω + 75 k Ω ) = 60 ( 25000 25000 + 75000 ) { ∵ 1 k = 1000 } = 60 ( 25000 100000 ) = 15 V For t ≥ 0 , the value of R eq = 25 k Ω . Consider the general expression to find the value of time constant for R C circuit. τ = R eq C Substitute 25 k Ω for R eq and 5 nF for C as follows
