1.R1 is in series with D1,C1,Lamp. Lamp,C1,D1 are in parrallel with each other. | |
2.L1 is in parallel with Neon Lamp.SW1 and R1 are in series | |
3.Guaranteed Same Voltage: all components. | |
Guaranteed Same Current: Voltage is not guaranteed to be the same, so current is not guaranteed to be the same accross all components. | |
4. Yes, I would expect the potential stored in the battery to be decimated as the voltage does work. This explains why batteries become useless if they are not recharged | |
5.9V*3A=27Watts dissipated. 3ohms resistance. 9V=3A*_Ohms | |
6.when in series add the voltages. the circuit on the left would have a Voltage of 9V. When in parallel the main circuit would be 6V, and it would try to charge the 3V battery. Which might destroy the voltage source in the real world. | |
7.When you add currents in series (figure on the left): The rest of the series circuit will have the greatest amount of current available. In this case, that would be 6A. | |
when you add currents in parrallel (figure on the right): The currents add, so the circuit will be ~8A. | |
