  1. Skip a page in your CRCT notebook. Week 30 1. What is voltage? • a measure of electric current • a kind of static electricity • a kind of current electricity • a measure of potential energy difference

  2. 2. In a circuit, a battery is • a conductor • an energy source • a load • an insulator

  3. 3. What is the purpose of a switch in an electric circuit? • to change the direction of the current • to provide a push for the current • to allow the electric circuit to be opened or closed • To increase the electric power to the load

  4. 4. What types of energy does a generator convert between? • electrical to mechanical • electrical to magnetic • magnetic to electrical • mechanical to electrical
