Electric Circuits: Batteries and Resistors
8. What will the ammeter read for the circuit shown to the right? 9. Draw the schematic of the following circuit.
10. What does the ammeter read and which resistor is dissipating the most power? 11. Analyze the ciruit below.
a. Find the current going out of the power supply b. How many Joules per second of energy is the power supply giving out? c. Find the current going through the 75 ? light bulb. d. Find the current going through the 50 ? light bulbs (hint: it's the same, why?). e. Order the light bulbs in terms of brightness f. If they were all wired in parallel, order them in terms of brightness. 12. Find the total current output by the power supply and the power dissipated by the 20? resistor.
