Power and energy change

?
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
