1 of 3
Wire A and wire B (not shown) both have the same resistivity and the same resistance. Wire B is twice as long as A. The radius of wire B must be
1. Half that of A.2. Greater than half, but less than A.3. Equal to that for A.4. Greater than A, but less than twice.5. Twice that for A.

Each light bulb as resistance R. The resistance presented to the battery by the light bulbs in circuit B is
1. Twice that seen in circuit A.2. Equal to that seen in circuit A.3. Half that seen in circuit A.4. Undeterminable without knowing the current.
