➹ Ratio of potential difference applied to the current
➹ measure of how difficult it is for an electric current to pass the conducting materials

# data[].attributes.body
➹ Amount of electrical energy converted to other forms of energy when each unit charge passes through a component.

◦ Component can be light bulb, resistors, variable resistors, etc.
◦ volt (V)

# data[].attributes.body
➹ Work done by a source in driving a unit charge around a completed circuit

◦ volt (V) or joules per coulomb (J/C)

E= e.m.f (V)
W= work done (J)
Q= charge (C)

# data[].attributes.body
1) ELECTRON FLOW : Movement of electrons from the negative to the positive terminal of an electric source.
2) CONVENTIONAL CURRENT: Flow of positive charges from the positive terminal to the negative terminal of an electric source.

# data[].attributes.body
➹ A rate of flow of electric charge past a given point in a circuit

◦ Current flows from the positive terminal to the negative terminal
◦ Ammeter : connected in series
◦ ampere/amps (A) or (coulombs/sec)

Q= charge (C)
I=  current (A)
t=  time (s)
