A 1 kOhm resistor is in series with a 1 muF capacitor.
a. What is the RC time constant of resistor-capacitor pair?
b. The 1 muF capacitor is charged from a 10 V battery via the 1 kOhm resistor. How long does it take for the voltage on the capacitor to reach 6.3 volts?
c. The 1 muF capacitor is charged from a 10 V battery via the 1 kOhm resistor. What is the voltage on the capacitor after one second?
