Capacitors Questions 0.0 / 5 ? PhysicsCapacitorsA2/A-levelAQA Created by: ashjackCreated on: 12-04-18 14:10 What is capacitance? Capacitance is the amount of charge that a capacitor can store per unit potential difference across it 1 of 5 What does each symbol mean in C=Q/V C=Capacitance (Farads), Q=Charge (Coulombs), V=Potential Difference (Volts) 2 of 5 Why aren't capacitors used as batteries? Because they can only store a tiny amount of charge, making it impractical to make a capacitor on the scale of a battery 3 of 5 What does each symbol mean in E=(1/2)(QV) E=Energy Stored (Joules), Q=Charge (Coulombs), V=Potential Difference (Volts) 4 of 5 What is a dielectric material? An insulating material that separates the two conducting plates of a capacitor 5 of 5
