1.) If the negative terminal of one battery is wired to the positive terminal of a second, the batteries are connected in series __________.
2.) A solenoid requires 24V at .25Amps. This solenoid must be operated from a 40 Volt power supply. What is the resistance value that must be placed in series with the solenoid?
3.) In a series circuit with 2 resistors R1 and R2, what voltage is measured across R2 if R1 opens?
Thanks for any help with these questions. Sorry, I just don't understand them.
