Questions & Step-by-Step Solutions
A capacitor is charged to a voltage of 10V and then connected to a resistor. What will happen to the voltage across the capacitor over time?
Step 1: Start with a charged capacitor at 10V.
Step 2: Connect the charged capacitor to a resistor.
Step 3: Understand that the capacitor will start to discharge through the resistor.
Step 4: Know that as the capacitor discharges, the voltage across it will decrease.
Step 5: Recognize that this decrease in voltage happens quickly at first and then slows down over time.
Step 6: Remember that the voltage decreases in an exponential manner, meaning it drops rapidly at first and then levels off.
Capacitor Discharge – The process by which a charged capacitor releases its stored energy through a resistor, resulting in a decrease in voltage over time.
Exponential Decay – The mathematical model that describes how the voltage across the capacitor decreases exponentially as it discharges.
