Multiple Choice

A resistor is made out of a wire having a length L. When the ends of the wire are attached across the terminals of an ideal battery having a constant voltage V0 across its terminals, a current I flows
Through the wire. If the wire were cut in half, making two wires of length L/2, and both wires were
Attached across the terminals of the battery (the right ends of both wires attached to one terminal,
And the left ends attached to the other terminal) , how much current would the battery put out?

• A) I
• B) I/4
• C) I/2
• D) 4I
• E) 2I
