Ohm's Law At MyOwnElectronicTrix.com
Table Of Definition |
|
| V = | Voltage in volts |
| A = | Electric current in amps |
| R = | Resistance the opposition of electrical current in ohms |
| P = | Power measured in watts |
V = |
A x R | A = |
V / R |
| P / A | P / V | ||
| SQRT ( P x R ) | SQRT ( P / R ) | ||
R = |
V / A | P = |
V x A |
| V² / P | V² / R |
||
| P / A² | A² x R |
For Example: If you're operation an appliance that uses 1200 watts at 120 volts AC, what is the current drawn in amp? 10 amp = 1200 Watts / 120 Volts What is the resistance in ohms? 12 Ohms = 120 Volt² / 1200 watts |
