The correct answer is: B. Surge protector
A surge protector is a device that is designed to protect electrical devices from voltage spikes. It does this by diverting the excess voltage to the ground. This prevents the voltage spike from damaging the electrical device.
A voltage unloader is a device that is designed to protect electrical devices from voltage drops. It does this by providing a temporary source of power to the device when the voltage drops below a certain level.
A heat protector is a device that is designed to protect electrical devices from overheating. It does this by shutting off the power to the device when it reaches a certain temperature.
A current unloader is a device that is designed to protect electrical devices from current spikes. It does this by diverting the excess current to the ground. This prevents the current spike from damaging the electrical device.
Here are some
additional details about surge protectors:- Surge protectors are typically made up of a series of metal oxide varistors (MOVs). MOVs are devices that change their resistance in response to changes in voltage. When a voltage spike occurs, the MOVs change their resistance and divert the excess voltage to the ground.
- Surge protectors are typically rated for a certain amount of voltage. This is the maximum amount of voltage that the surge protector can handle without being damaged.
- Surge protectors should be used with all electrical devices, but they are especially important for devices that are sensitive to voltage spikes, such as computers and televisions.
- Surge protectors can be purchased at most hardware stores.
