At the instant a circuit is connected, the current is at its maximum value, which is given by I = V/R. After that moment, the current decreases as the capacitor charges according to this equation: I = Io e^-t/τ where Io is the initial current through the circuit.
a. A capacitor (C = 10 μF) is in a series circuit with a resistor (R = 100 Ω). They are attached to a battery (V = 120 V). What is the initial current when the circuit is switched on? (1 point)
b. What is the current through the circuit after 2 milliseconds? (1 point)
c. What is the voltage across the resistor after 2 milliseconds? (1 point)
d. Based on your answer to part (c), what must be the voltage across the capacitor after 2 milliseconds? (1 point)
e. What is the charge on the capacitor after 2 milliseconds? (1 point)
f. At what time will the current through the circuit have decreased by 95%? (1 point)
g. Write an equation that tells you the voltage across a capacitor at any given time as it is charging. (1 point)
h. What will the voltage across the capacitor be when the current has decreased by 95%? (1 point)
