A battery is connected to two wires in parallel. Both wires are made of the same material and are of the same length, but the diameter of wire A is twice the diameter of wire B. Select true or false for each statement.

The voltage drop across wire B is larger than the voltage drop across wire A.

The power dissipated in wire A is 16 times the power dissipated in wire B.

The current through the battery is five times larger than the current through wire B.

The resistance of wire B is twice as large as the resistance of wire A.
The resistance of wire B is four times as large as the resistance of wire A.
