if i have two components in a series circuit and the resistance across one drops, does the pd across the other one increase?

The relationship between Pd (voltage) and resistance is known as Ohm's Law, which states that the voltage across a resistor is directly proportional to the current flowing through it, while the resistance remains constant.
Changing the resistance in a circuit will cause a corresponding change in the voltage. If the resistance increases, the voltage will also increase, and vice versa. This is because the higher the resistance, the more difficult it is for current to flow, resulting in a higher voltage drop.
When the resistance is at its maximum, the voltage will also be at its maximum, and when the resistance is at its minimum, the voltage will also be at its minimum. This is because the voltage drop across a resistor is directly proportional to the resistance.
In theory, Pd (voltage) and resistance can be equal, but this would result in no current flowing through the circuit. In practical applications, it is not desirable for Pd (voltage) and resistance to be equal, as this would lead to a non-functioning circuit.
Pd (voltage) can be measured using a voltmeter, while resistance can be measured using an ohmmeter. These tools are commonly used in circuit analysis to determine the values of Pd (voltage) and resistance in a circuit.
