Derivations
Use the formulas below to drive the following equations.
Charging a Capacitor
- Charge on a capacitor as a function of time, q(t)
HINT - See below. - Potential across the capacitor as a function of time, V(t)
- Current as a function of time, i(t)
HINT - differentiation - Potential across the resistor as a function of time, V(t)
Discharging a Capacitor
- Charge on a capacitor as a function of time, q(t)
HINT - Use i = -dq/dt - Potential across the capacitor as a function of time, V(t)
- Current as a function of time, i(t)
HINT - differentiation - Potential across the resistor as a function of time, V(t)
