A capacitor discharges through a resistor. At time t=0t = 0t=0, the charge stored by the capacitor is 800 μC800\ \mu\text{C}800 μC. The capacitor loses 8.0% of its charge every second.
What is the charge left on the capacitor at time t=3.0 st = 3.0\text{ s}t=3.0 s?
177 μC177\ \mu\text{C}177 μC
608 μC608\ \mu\text{C}608 μC
623 μC623\ \mu\text{C}623 μC
736 μC736\ \mu\text{C}736 μC
