Question

A resistor with a resistance of 4.0 MO and a 9.0 µF capacitor are in series with a battery with an emf of 9.0 V. Determine the following quantities 2.1 s after the connection is made.
a) What is the rate at which the charge of the capacitor is changing? Incorrect: Your answer is incorrect.

b) What is the rate at which energy is being stored in the capacitor?

c) What is the rate at which thermal energy is being produced in the resistor?

d) What is the rate that energy is being delivered to the circuit by the battery?

Explanation / Answer

Since Q=CV
and V=1/Cintergration of(idt)

You have to use equation to determine the current

it will be 4i(t)+1/C integration of (idt)=9

put the values and find the equation of current
