energy transfer in appilances. Flashcards
1
Q
whenever a charge flows what does it need to overcome?
A
resistance of the circuit.
2
Q
work is done when?
A
charge flows.
3
Q
the amount of energy depends on what?
A
amount of charge that flows and the potential difference.
4
Q
the amount of energy transferred can also be found where?
A
from the power of the appliance and how long it is used for.
5
Q
what is the formulas for energy transferred?
A
energy transferred = power × time.
energy transferred= charge flow × potential difference.
