MULTIPLE CHOICE QUESTION

A 9.0-V battery is connected to a 3.5-Ω resistor and a 2.5-Ω resistor connected in series. Which statement is true?

The total electric potential and the electric potential for each resistor is the same.

The total current out of the battery and the current through each resistor is the same.

The total current out of the battery gets split up among the resistors.

Each resistor outputs the same power.

Answer explanation

Only one path for current to flow on in a series circuit means the amount of the current is the same throughout the circuit.

The current going through the 8.0-Ω resistor is ___ A.

Mathematical Equivalence

ON

Answer explanation

Series connections for the resistors means the total resistance is:

Rtot = 8.0 + 16.0 + 6.0

Rtot = 30.0 Ω

Ohm's Law is used to find total current:

12 = I·30.0

0.40 A = I

Suppose light bulb and socket C was removed from the circuit shown. Wire is used to connect the switch to light bulb and socket B instead. What will happen to the total voltage of the battery when this happens?

It will stay the same.

It will increase so the bulbs A and B burn brighter.

It will decrease so the bulbs A and B will dim.

The circuit cannot work without light bulb and socket C where it is.
