You have 3 resistors available, two are 125 ohm resistors and one is 250 ohm
a. What is the total resistance of a circuit which contains all 3 resitors in series?
b. If all three resistors are connected in series to a 12V battery, what are the voltages across each resistor and the current through each resistor?
c. What is the total resistance of a circuit which contains all 3 resistors in parallel?
d. If all 3 resistors are connected in parallel to a 12V battery, what are the voltages across each resistor and the current through each resistor?
