Power and energy change 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: nimrahali12Created on: 30-10-16 14:47 The formula for electrical power is? power=current times potential difference 1 of 9 Whats the equation? P=I TIMES V 2 of 9 The potential difference is the energy transferred per? charge passed 3 of 9 Energy is supplied to the change at the power source to? raise it through potential 4 of 9 The charge gives up this energy when it 'falls' through any potential drop in? components elsewhere in the circuit 5 of 9 What is the formula? Energy transformed=charge times potential difference 6 of 9 The bigger the change in PD , the more energy is? transferred for a given amount of charge passing through the circuit 7 of 9 That means? that a battery with a bigger voltage will supply more energy to the circuit for every coulomb of charge which flows round it 8 of 9 Because? the charge is raised up higher at the start and as the diagram shows more energy will be dissipated in the circuit too 9 of 9
