R= V / I

= 15 (v) / 12 ( A)

= 1.25 Ohm   Reply #### Brandonleewoodhouse

1.25 ohms

Multiply the current by the electrical resistance to calculate the voltage. For example, if the current is 2.5 amperes and the resistance is 15 ohms, then the voltage = 2.5 amperes x 15 ohms = 37.5 volts.   Reply Search for Google images Select a recommended image
