Describe the charging process in an RC circuit.
The charging process in an RC circuit involves the capacitor initially acting as an open circuit, preventing current flow through the resistor.
The charging process in an RC circuit involves the capacitor charging instantly to its maximum voltage, bypassing the resistor.
The charging process in an RC circuit involves the capacitor initially acting as a short circuit, allowing current to flow through the resistor. As the capacitor charges up, the voltage across it increases, and the current decreases until it reaches its maximum value, following an exponential curve until fully charged.

Explain the discharging process in an RC circuit.
The resistor in an RC circuit absorbs energy during the discharging process.
The discharging process in an RC circuit involves the capacitor storing energy indefinitely.
The discharging process in an RC circuit involves the capacitor releasing stored energy through the resistor, causing the voltage across the capacitor to decrease exponentially until it reaches zero.
During discharging, the voltage across the capacitor increases linearly.
