1.

We're told that the resistors are equal and connected in series.

This means that equal current will flow through each of them.

###### Problem Details

1. Three identical resistors are connected in series to a battery. If the current of 12 A flows from the battery, how much current flows through any one of the resistors?
a) 12 A
b) 4 A
c) 36 A
d) 24 A
e) zero

2. If you connect two identical storage batteries together in parallel, and place them in a circuit the combination will provide
a) twice the voltage and twice the total charge that one battery would.
b) twice the voltage and the same total charge that one battery would.
c) the same voltage and twice the total charge that one battery would.
d) half the voltage and half the total charge that one battery would.
e) half the voltage and the same total charge that one battery would

3. A current reading is obtained by properly placing an ammeter in a circuit consisting of one resistor and one battery. As a result,
a) the voltage drop across the resistor increases
b) the current flowing in the circuit increases.
c) the current flowing in the circuit decreases
d) the current flowing in the circuit does not change
