Question
![**RC Circuit Analysis**
Consider a series RC circuit as shown in the figure, where the components have the following values:
- Resistance, \( R = 6.00 \, \text{M}\Omega \)
- Capacitance, \( C = 1.00 \, \mu\text{F} \)
- Electromotive force, \( \varepsilon = 32.0 \, \text{V} \)
### Tasks:
(a) **Find the time constant of the circuit.**
- Time constant (\( \tau \)) is calculated using the formula \( \tau = RC \).
(b) **What is the maximum charge on the capacitor after the switch is thrown closed?**
- Maximum charge (\( Q \)) on a fully charged capacitor is found using \( Q = C\varepsilon \).
(c) **Find the current in the resistor 10.0 s after the switch is closed.**
- The current (\( I \)) in the resistor can be determined using the exponential decay formula for current in an RC circuit:
\[
I(t) = \frac{\varepsilon}{R} e^{-t/RC}
\]
Evaluate this expression at \( t = 10.0 \, \text{s} \).
These calculations assist in understanding the behavior of the circuit over time, providing insights into the charging and discharging processes within the circuit.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F99e37c92-095a-4cae-adf6-01aeaaa5668c%2F03d9d5ea-2a6b-4cb0-a747-90e6b4357f4e%2F6nlwhcw_processed.png&w=3840&q=75)
