Question

A 9-volt battery is attached to a series circuit consisting of a 10-ohm resistor and 1-farad capacitor and a switch. when

the switch closes the circuit, describe the original and final current through the circuit.
a)
the initial current is 9 amps and final current is o amps.
b)
the initial current is 0 amps and final current is 9 amps.
c)
the initial current is 0.9 amps and final current is o amps.
d)
the initial current is o amps and final current is 0.9 amps.

Answer 1

c

Step-by-step explanation:

Initially the capacitor just acts as a short circuit...or piece of wire ...just like it is not there.... so initially current = V/R = 9/10 = .9 amps

as the capacitor charges to full capacity the current gradually decreases to

0 amps
