This chart shows four ways to figure each value:
Amps (1), Volts (E), Ohms (R), or Watts (W)
| Example: | ||
| A 4800 watt electric heat element is connected to a 240 volt circuit. | ||
| How many Amps (1) does it draw? | ||
| Solution: | ||
| Locate Amps section of chart- | ||
| Watts (W) | = Amps (1) | |
| Volts (E) | ||
| Thus 4800 / 240 = 20Amps. Carried further, what is the resistance? | ||
| Volts(²) (E²) | = Ohms (R) 240 x 240 / 4800 = 12 Ohms | |
| Watts (W) | ||
