Mayor
Thank you for being willing to help us. The village is having some mosquito problem that has raised concerns about dengue. We actually have an electrical mosquito repellent device but it malfunctioned after a monkey managed to steal it from the town hall a few days ago. We've retrieved the device but we have no idea why it doesn't work anymore.
The Really Rather Important Device

Device
The device has a missing panel. Looking into the device, there are 2 wires dangling freely. Most probably, something that connected these 2 wires together was removed.

Manual
The manual refers to the missing portion as a resistance that regulated the amount of current flowing through the device. For maximal operation, the device should have 65.45 mA of current.

Battery
The voltage across the two points is 9 V.

Resistors
The town has a limited supply of resistors. In fact, they only have 6 100Ω resistors.
