For question 1, do you know what the terms “parallel” and “series” mean? If so, just think about what you would use to shut off the power to the WHOLE system.

For questions 2 and 3, these can be answered by solving the very basic electrical equation V=IR, where “V” is voltage, “I” is current and “R” is resistance. (Ohm’s Law)
