current
The rate of flow of charge around a circuit
efficiency
The fraction of energy that is used for its intended
purpose.
elastic energy
The energy associated with amount an object is
stretched.
Gravitational potential energy
The energy associated with the height an object is
raised.
kinetic energy
The energy associated with the movement of an object.
Non - renewable
A resource of which there is only a limited amount, which
will run out
potential difference
The amount of energy given per unit charge
power
The amount of energy transferred per second, measured
in Watts (W).
Renewable
A resource that will not run out.
Resistance
A quantity that indicates how much current is slowed
down by.
Store
On object that stores energy.
Transfer
Giving of an amount of a quantity from one object to
another
Transformer
An electrical device that is used to either increase or
