Period 14 Exercises: Electric Current and Capacitance Write answers to the questions below. Show your mathematical steps and the units of the quantities. This sheet with your answers should be turned in at the beginning of Period 15. 1. Identifying the elements of electric circuits: a)- What is the difference between electric charge and electric current? b) What devices could produce a voltage boost (electrical energy increase) in a circuit? c) What happens to the voltage boost in an operating electric circuit? d) What conditions are necessary for an electric circuit to light a bulb? 2. Using ratios to solve problems: A 1.0 farad capacitor stores about 5 joules of electrical potential energy. How many such charged capacitors would it take to equal the 0.7 million joules of chemical energy stored in a bottle of gasoline the size of one of these capacitors
