Flashcards in Power and Enegry Change Deck (6):
1

Potential difference is the energy transferred per [ ]

charge passed

2

When electrical charge (Q) goes through a [ ], then energy (E) is transferred

change is potential difference (V)

3

Energy is supplied to the charge at the [ ] to 'raise' it trough a [ ]. The charge gives up this energy when it 'falls' through any potential drop in [ ] elsewhere in the circuit

4

What is the formula for energy transformed?

energy transformed (J)= Charge (C) * P.D (V)

5

The bigger the change in p.d the [ ] energy is transformed for a given amount of [ ] passing though a circuit

more
charge

6

A battery with a [ ] voltage will supply more energy to the circuit for every [ ] which flows around it, because the charge is raised up 'higher' at the start - more energy will be [ ] in the circuit too

bigger
coulomb of charge
dissipated
