Flashcards in Power and Enegry Change Deck (6):
Potential difference is the energy transferred per [ ]
When electrical charge (Q) goes through a [ ], then energy (E) is transferred
change is potential difference (V)
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
What is the formula for energy transformed?
energy transformed (J)= Charge (C) * P.D (V)
The bigger the change in p.d the [ ] energy is transformed for a given amount of [ ] passing though a circuit
