Question 1 How many electrons pass a fixed point in a 100-watt light bulb in 1 hour if the applied constant voltage is 120 V? Question 2 The average current in a typical lightning thunderbolt is 2 × 10* A and its typical duration is 0.1 s (Williams, 1988). The voltage between the clouds and the ground is 5 x 108 V. Determine the total charge transmitted to the earth and the energy released. (Reference: Williams, E. R. 'The Electrification of Thunderstorms', Scientific American, Nov. 1988. pp. 88 – 89.) Question 3 A unit of power used for electric motors is the horsepower (hp), equal to 746 watts. How much energy does a 5-hp motor deliver in 2 hours? Express the answer in MJ. Question 4 A conductor has a constant current of 5 amperes. How many electrons pass a fixed point on the conductor in 1 minute? Question 5 A certain circuit element has the current and voltage as follows: i = 10e-5000t A v = 50(1 – e-5000Ł) V Find the total energy transferred during t 2 Os.
