2
Q
Inductance
A
A measure of magnetic flux produced for a give electrical current
3
Q
Capacitance
A
A measure of how much electrical charge is stored for a given voltage
4
Q
Voltage
A
The difference of electrical potential between two points. SI unit Volts (V)
5
Q
Power
A
In electrical terms can be quantified as the work done by an electrical current per unit time SI unit watts (W)
6
Q
Resistance
A
Is the measure of opposition to the flow of electrical current which a material possess SI unit is the ohm (Ω)
7
Q
What can affect the energy in a electrical devices
A
Energy losses in an electrical system may occur due to resistance of conductors producing heat.
