A Voltage Source of 10

Multiple Choice

A voltage source of 10.0 V is connected to a series RC circuit where R = 2.80 × 10⁶ Ω,and C = 3.50 µF.Find the amount of time required for the current in the circuit to decay to 4.00% of its original value.Hint: This is the same amount of time for the capacitor to reach 96.0% of its maximum charge.
