So that there is no net movement/in equilibrium 5 of 12 What is the centre of gravity Where gravitational force acts on a body 6 of 12 What is power the rate of energy transfer measured in watts 7 of 12 What is the conservation of energy Energy is not lost or gained just transformed into another form 8 of 12 State Ohm's law The current through an ohmic device is directly proportional to the pd across it provided the temperature is constant 9 of 12 What is resistance The forces that oppose the flow of electron current in a conductor 10 of 12 What is a super conductor A conductor with no resistance at absolute zero 11 of 12 what is the conservation of charge the current going into a junction is equal to the current leaving the junction 12 of 12
