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
identied 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.
