Power / Voltage / Current Calculations

These formulas are used to calculate the wattage, or current, drawn by a particular circuit or device.

The power (in watts) dissapated by a device equals the current (in amperes) times the voltage (in volts). So

          P = I * E
          I = P / E
          E = P / I
