I. VOCABULARY If the underlined word is used incorrectly, cross it out and replace it with the correct word. 1. The rate of flow of electric charge is called resistance and it is measured with the unit joule. 2. Current is the electric potential energy per charge. It comes from the wires. The unit is the ohm. 3. Resistors in a circuit increase the flow of charge. This obstruction is called voltage. 4. Resistors dissipate mechanical energy into heat. The rate at which this occurs is called load. 5. In a series circuit each resistor has the same voltage.
