The voltage across each resistor in a series circuit is the same. Therefore, if the input voltage is 12 V and there are n resistors in the circuit, the voltage across each resistor will be:
V = 12 V / n
For example, if there are three identical fixed resistors in the circuit, the voltage across each resistor will be:
V = 12 V / 3 = 4 V
Will set up the following series circuit with identical fixed resistors. What is the voltage across each resistor if the input voltage is 12 V?
