An uncharged capacitor is connected to a resistor and a battery. Choose what happens to current, potential difference and charge right after the circuit is closed. An uncharged capacitor is connected to a resistor and a battery. Choose what happens to current, potential difference and charge right after the circuit is closed. Potential difference across the capacitor starts high and then drops exponentially.
Current through the circuit starts with zero and then increases gradually to a maximum value.
Charge on the plates of the capacitor decreases with time.
Charge on the plates of the capacitor increases with time.
Charge on the plates of the capacitor doesn't change with time.
Potential difference across the capacitor starts with zero and then increases gradually to a maximum value.
Current through the circuit starts high and then drops exponentially.
