Two electrodes connected to a 9.0 v battery are charged to ±45 nc. what is the capacitance of the electrode?

Explanation:

The capacitance of the electrode is given by:

where

C is the capacitance

Q is the charge on the electrode

V is the potential difference

In this problem, we have

V = 9.0 V

Substituting into the equation, we find

(5 nF)
