Conversion Tables
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) |
