Ohms Law

Enter any TWO of the following values, then press the SOLVE button 
Voltage = volts
Resistance = ohm
Current = amps
Power = watts
Ohms Law:  E = IR
Power:  P = IE
  E is voltage (measured in volts)
  I is current (measured in amperes)
  Ris resistance (measured in ohm-cm)
  Pis power (measured in watts)
The following may help determine all the combinations and permutations of Ohms Law and the formula for power.
