The current through a 83 m long wire connected to a battery is 2.3 A. A section of the wire is cut off and used to build a circuit. When the remaining wire is connected to the same battery as before the current in the wire is 3.3 A. How much wire is left?
Two resistances, R1 and R2, are connected in series across a 12-V battery. The current increases by 0.25 A when R2 is removed, leaving R1 connected across the battery. However, the current increases by just 0.10 A when R1 is removed, leaving R2 connected across the battery. Find (a) R1 and (b) R2.
