Voltage, Energy & Power includes the following learning objectives:

  • Distinguish between potential difference and electromotive force;
  • Define the volt as 1V = 1JC??;
  • Use a cathode ray oscilloscope (c.r.o) to measure voltage;
  • Recall and use W = QV;
  • Use the kilowatthour (kWh) as a unit of energy;
  • Recall and use the equations for power, P = IV = I?R = V?/R
  • State and use the expression for efficiency; understanding that it is a ratio and is expressed as a percentage.
