Find The
Volts, Amps, Ohms, Watts


Volts = V or E
1. A times R = V
2. W divided by A = V
3. Square root of W times R = V
Amps = A or I
1. V divided by R = A
2. W divided by V = A
3. Square root of W divided by R = A
Ohms = R or O
1. V divided by A = R
2. V squared divided by W = R
3. W divided by A squared = R
Watts = W or P
1. V times A = W
2. V squared divided by R = W
3. R times A squared = W

Battery Voltage & Charge

Open Circuit Voltage VS. State of Charge
12.66V = 100%
12.45V = 75%
12.24V = 50%
12.06V = 25%
11.89V = 0%
