What happens to the current in the circuit.? (5pts.) J. Over the course of a 12-hour day, 5.2 210" C of charge pass through a typical computer. Determine the current for such a computer. (2pts.) 4. Determine the amount of time that the following devices would have to be used before 10x10 CCI million Coulombs] of charge passes through them. (Spis.) ". LED light (1 0 01084 A) b. Incandescent light (1-0.034 A) c. 60-Want incandescent light bulbs (1-0.25 A) d. Bathroom light (1-10 A) 3. Determine the overall resistance of . 50-meter length and a 0.143 cra diameter wire made of the following materials. (5pti.) a. copper (resistivity = 1 67x10' 0.mj b. silver (resistivity = 1.59x10' 0.m) c. aluminum (resistivity = 2.65x10* 0.m) d iron (realstivity - 9.71210' 0.m) 6. Calculate the amount of power dissipated by an electric heating element if the generator's output vollage is 110 volts and the hester's resistance is 2.5 ohms. Then, calculate the power dissipated by the same heater if the generator's outpul vollage is doubled. (3pis.) 7. Describe and explain the relationship of current, vollage and resistance. (10pts.)
