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

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
