Hi, here's my question.

26.39: A capacitor is charged to a potential of 12.0 V and is then connected to a voltmeter with an internal resistance of 3.40 MW. After a time of 4.00 s, the voltmeter reads 3.0 V. What are **(a)** the capacitance and **(b)** the time constant of the circuit?

Step 1

(a) The voltage across the capacitor is

Step 2
