(WILL AWARD POINTS AND MOST BRAINY)
1. A series circuit contains an electric generator, three devices operated by electricity, and the necessary connecting wires. The resistances of the three devices are 20 ohms, 8 ohms, and 4 ohms. The resistance of the connecting wires can be neglected. What is the total resistance in the circuit?
2. If the terminal voltage developed by the generator in question 1 is 110 V and the resistance of the generator is neglected, what current will flow through the circuit? Round your answer to two decimal places.
3. For the conditions described in questions 1 and 2, what will be the voltage drop in the device having a resistance of 8 ohms? Round your answer to one decimal place.
4. If the three electrical devices in question 1 are connected in parallel, as shown in the figure, what will be the total resistance of the group of devices? Round your answer to two decimal places.
5. Assume that the voltage developed by the generator in the circuit in question 4 is 110 V. If the resistance of the generator and the connecting wires is neglected, what current will flow through the wires between the generator and the group of three devices? Round your answer to one decimal place.
6. In the circuit in question 4, what portion of the total current will flow through the device that has a resistance of 8 ohms?
