RC Circuits
What is the time constant of the circuit shown in the figure below? Each of the five resistors has resistance R, and each of the five capacitors has capacitance C. The internal resistance of the battery is negligible.
Practice!
| Practice 8.4.1 |
|---|
The two circuits shown contain identical fully charged capacitors at t = 0. Circuit 2 has twice as much resistance as circuit 1. Compare the charge on the two capacitors a short time after t = 0. |
| Practice 8.4.2 |
|---|
Consider the circuit shown in the figure and assume the battery has no internal resistance. Just after the switch is closed, what is the current that flows through the battery? |
| Practice 8.4.3 |
|---|
| Consider the circuit shown in the figure and assume the battery has no internal resistance. A very long time after the switch has been closed, what is the current that flows through the battery? |
