Unformatted text preview: voltage and uses the symbol (V). 1 Volt = 1 Joule / Coulomb Voltage Symbols Units V = voltage Volts (V) W = work (PE) Joules (J) q = charge Coulomb (C) q W V = Example #1 If a conductor connected to the terminal of a battery has a potential difference (voltage) of 12 V, what is the potential energy of each coulomb of charge? Example #2 If a charge of 2 x 10-5 C has a PE of 540 J, what is its voltage? 3 Example #3 If a rubber balloon is charged to 5000 V, and the amount of charge on the balloon is 1 x 10-7 C, what is the potential energy of this charge? Example # 4 A force of 0.032 N is required to move a charge of 4.2 x 10-6 C in an electric field between two points which are 0.25 m apart. What is the potential difference (voltage) between the points?...
