I bolded the answer I think is correct - I'm just a little unsure on these, any help would be appreciated!
1. A capacitor and resistor are connected in a series with a batter and a switch. The instant after the switch is closed
A. the voltage across the resistor is equal to the emf of the battery
B. the voltage across the capacitor is equal to the emf of the battery
C. the voltage across the resistor is equal to zero
D. the current is equal to zero
E. both A and B are correct
2. The figure below shows a set of equipotential lines. The electric field has the greatest magnitude at point

A. A
B. B
C. C
D. D
E. E
3. Four charges are arranged on the corners of a square as shown below:

At which point (or points) is the electric field equal to zero?
A. B and E
B. D and A
C. A and C
D. A and B
E. E only
