Question

For a simple RC circuit, which of the following statements is correct regarding this graph? (Select all that apply.)

During the charging process the current flows through the resistor in the opposite direction and therefore the potential difference across the resistor will be negative.

During the discharging process the current flows through the resistor in the opposite direction and therefore the potential difference across the resistor will be negative.

The positive values represent the potential difference across the resistor during the charging process.

The positive values represent the voltage across the resistor and the negative values represent the voltage across the capacitor.

The positive values represent the voltage across the capacitor and the negative values represent the voltage across the resistor.

Explanation / Answer

while charge charge Q = Qo (1 - e^-t/RC)

while discharging Q = Qo e^-t/RC

current while chargeing is given by i = io e^-t/RC

while discharging, I = io e^-t/RC

so

During the discharging process the current flows through the resistor in the opposite direction and therefore the potential difference across the resistor will be negative.

The positive values represent the potential difference across the resistor during the charging process.
