Ohm’S laW

The ElectriCalc Pro’s built-in Ohm’s Law functions allow you to easily 

solve for Voltage (Volts), Current (Amps), or Resistance (Ohms) by 

entering in any two variables (e.g, Volts and Amps) and solving for 

the third (e.g., Ohms).

Ohm’s Law: V = I x R

The Ohm’s Law functions on the ElectriCalc Pro are  

identified as follows:

• Vdc = Voltage, in Volts 

• Idc = Current, in Amps 

• R = Resistance, in Ohms

finding Volts

The Current in a circuit is 0.0125 Amps, and the total Resistance is 

480 Ohms. Find the Voltage.
