Explanation Calculation: Refer to Figure in the respective question. Redraw the Figure as shown in Figure 1 for t < 0 . From Figure 1, Find v c ( 0 ) . v c ( 0 ) = 3 15 ( − 75 ) = − 15 V Redraw the Figure as shown in Figure 2 for 0 ≤ t ≤ 800 μ s . From Figure 2, Find the equivalent resistance. R e q = ( 4 k Ω + 2 k Ω ) ∥ ( 3 k Ω ) = ( 6 k Ω ) ∥ ( 3 k Ω ) = ( 6000 ) ( 3000 ) 6000 + 3000 = 18 × 10 6 9000 Simplify the equation as follows. R e q = 2 × 10 3 = 2 k Ω From Figure 2, write the expression for time constant. τ = R e q C Substitute 2 k Ω for R e q and 0.5 μ F for C as follows. τ = ( 2 k Ω ) ( 0.5 μ F ) = ( 2 × 10 3 ) ( 0.5 × 10 − 6 ) = 1 × 10 − 3 = 1 ms Rearrange the equation as follows. 1 τ = 1 1 ms = 1000 From Figure 2, write the expression for v c . v c = v c ( 0 ) e − t τ Substitute − 15 V for v c ( 0 ) and 1000 for 1 τ as follows. v c = − 15 e − 1000 t V Substitute 800 μ s for t as follows. v c = − 15 e − 1000 ( 800 μ s ) = − 15 e − 1000 ( 800 × 10 − 6 ) = − 15 e − 0.8 ≅ − 6.74 V Redraw the Figure as shown in Figure 3 for 800 μ s ≤ t ≤ 1.1 ms . From Figure 3, write the expression for time constant. τ = ( 2 k Ω + 4 k Ω ) ( 0.5 μ F ) = ( 6 k Ω ) ( 0.5 μ F ) = ( 6000 ) ( 0.5 × 10 − 6 ) = 3 × 10 − 3 s Simplify the equation as follows. 1 τ = 1 3 × 10 − 3 = 333.33 From Figure 3, write the expression for v c . v c = − 6.74 e − 333
