Capacitors

Question 1

Capacitance

Answer 1

The stored charge in a capacitor per unit potential difference across the plates.

Question 2

Farad

Answer 2

The capacitance of a capacitor which stored a charge of 1C when a voltage of 1V is across the plates.

Question 3

Capacitors in series

Answer 3

Same as resistors in parallel

Question 4

Answer 4

Same as resistors in series

Question 5

Capacitors in parallel

Answer 5

Same as resistors in series

Question 6

Capacitive time constant

Answer 6

The time taken for the current, charge and p.d. for a capacitor to fall to 1/e (37%) of its original value when discharging through a resistor.
τ = RC
