| work = | force x distance |
| The amount of work done is measured in | Joules |
| The rate at which energy is produced | is called power |
| One horesepower is equal to | 746 Watts. |
| Voltage = | energy divided by charge transferred |
| Current = | Charge transferred divided by time |
| Efficiency = | Energy Output divided by Energy Input |
| AC frequency is the number | of cycles in a second |
| In North America AC frequency | is 60 cycles per second |
| Bi-metallic strips are used in | circuit breakers |
| Bi-metallic strips bend due to | different coefficients of expansion |
| Polarized plugs have one prong | that is wider than the other |
| Electrical Power = | Voltage x Current |
| One hertz is equal to | one cycle per second |
