Web12 sep. 2024 · Basically, a resistor limits the flow of charge in a circuit and is an ohmic device where \(V = IR\). Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. Web12 mrt. 2024 · As you can see, only two terminals are used. It doesn’t matter which combination, as long as it is not terminal 1 and 3. Variable resistor function #2: Adjusting voltage (configuration 1) Adjusting voltage is the other main function of a variable resistor.. To achieve voltage control, all three terminals of the variable resistor will have to be used.
