Can a bad battery cause the alternator to get hot?

A bad battery can cause the alternator to get hot if it is not able to provide enough power to the vehicle. This can happen because the alternator has to work harder to keep up with the demand for power, which can cause it to overheat. Additionally, a bad battery can also cause the voltage regulator to malfunction, which can lead to overcharging of the battery and further increase the risk of the alternator overheating.
