PhysicsCapacitorsA2/A-levelOCR Created by: abbin003Created on: 19-12-19 07:53 Define capacitance The charge stored per unit p.d. 1 of 12 State the equation for capacitance C=Q/V 2 of 12 In which circuit where a capacitor is connected in parallel or series is, the total capacitance greater than the individual capacitances Parallel 3 of 12 Would capacitors connected in parallel store more charge for a given p.d. Yes 4 of 12 State the 3 equations linking capacitance with work done W=1/2 QV, W=1/2 V squared multiplied by C, W=1/2 Q squared /C 5 of 12 What does the capacitor discharge through A resistor 6 of 12 What happens to the p.d, the current and capacitances as time increases while the capacitor is discharging They all decrease 7 of 12 State an equation linking current with charge, capacitance and resistance I=-Q/CR 8 of 12 When discharging a capacitor do u connect a resistor in series or parallel Parallel 9 of 12 When charging a capacitor do you connect a resistor in parallel or series Series 10 of 12 When charging a capacitor as P.d. of capacitor increases what happens to the p.d. of the resistor and why P.d. Decreases because Kirchhoffs second law. ( give description of the law) 11 of 12 How much current is there across the circuit when the capacitor is fully charged 0 12 of 12
