A potential change in a battery/resistor system refers to the difference in electric potential between the two terminals of a battery. This potential difference is what causes an electric current to flow through the circuit, and is measured in units of volts.
A potential change can affect the performance of a battery/resistor system in a few different ways. If the potential change is too high, it can cause the battery to overheat and potentially damage the circuit. Conversely, if the potential change is too low, the battery may not be able to supply enough energy to power the circuit effectively.
Some factors that can cause a potential change in a battery/resistor system include the type and quality of the battery, the resistance of the circuit, and the amount of current flowing through the circuit. Changes in temperature and external factors, such as corrosion or loose connections, can also impact the potential change.
A potential change can be measured using a voltmeter, which is a type of electrical measuring device. The voltmeter is connected to the two terminals of the battery and can accurately measure the potential difference between them, giving a reading in volts.
To prevent potential changes from negatively affecting a battery/resistor system, it is important to use high-quality components, properly maintain the circuit, and monitor the voltage levels regularly. Adding a resistor or other protective devices to the circuit can also help regulate potential changes and prevent damage to the system.
