|
Current |
The rate of flow of charge. (Q=It, Q=Charge/C, I=Current/A, t=time/s) 1A is equal to 1C passing a fixed point per second. |
|
|
Electromotive Force (EMF) |
The energy converted by a source into electrical energy when unit charge passes through it. E=V/Q E=EMF/V, V=Electrical Energy Converted/J, Q=Charge/C |
|
|
Potential Difference (PD) |
1) The electrical energy converted into other forms by a component in a circuit for each coulomb passing through it. 2) The PD between two points is the energy generated for every coulomb passing between them. W=QV W=Energy converted/J, Q=Charge/C, V=PD/V |
|
|
Resistance |
The opposition to the flow of charge. |
|
|
Electrical Power |
The rate at which electrical energy is converted to other forms by a component. P=IV P=Power/W, I=Current/A, V=PD/V |
