Explanation / Answer

Voltage across a Capacitor while charging is given by the equation,
V = Vo * (1 - e^(-t/RC))
Where,
V0 = 8.0 Volt
RC = 10 * 10^6 * 1 * 10^-6 = 10

(a)
At t = 1.0 s
V = 8.0 * (1 - e^(-1.0/10))
V = 0.76 Volt

(b)
At t = 5.0 s
V = 8.0 * (1 - e^(-5.0/10))
V = 3.15 Volt

(c)
At t = 20.0 s
V = 8.0 * (1 - e^(-20.0/10))
V = 6.92 Volt
