Question

1.) Consider an RC circuit, with values of R=1600Ω,V=6V, and C=3600μF .
Assume that the circuit starts with the capacitor fully discharged and begins charging at t=0.
What is the maximum current?
After what amount of time is the current at a fraction of 0.9 if its maximum value?

2.) Consider an RC circuit, with values of R=4100Ω,V=6V, and C=5000μF
Assume that the circuit starts with the capacitor fully discharged and begins charging at t=0.
What is the maximum current?
At time t = 1 s, what is the current?

3.) A uniform electric field of strength 1.12 N/C is set up across a parallel plate capacitor. The gap between the plates is 2 μmμm.
Assuming a uniform field between the plates pointing in the forward x direction, what is the potential difference across the capacitor? (Hint, is the potential increasing or decreasing)
