WebELECTRONIC COMPONENTS (a). Protecting components Resistors can be used to protect other components (such as an LED) from damage by too much current. (b). Potential dividers In a potential divider, a fixed resistor is used to split voltage between different parts of the circuit.Potential dividers (or voltage dividers) are used, for example, with LDR s in … WebJun 11, 2024 · Don't let the fact that there is a potentiometer in the circuit confuse you. In any one setting, you can replace the potentiometer with two fixed resistors. Once you have done that, you have a simple 4-resistor network to solve. Solve this at as many pot settings as you like to get a graph of voltage as a function of pot position.
