What is the voltage value of the voltmeter?
Voltage distribution in series connection
When two or more resistors are connected in series, the sum of the voltages applied to the resistors becomes the total voltage.
Therefore, the resistors divide the supplied voltage according to their resistance value.
If the series connected resistors have the same magnitude, the resistors take the supply voltage divided by \(1 \over n \).
If the resistors are different, a higher voltage is applied to the larger resistor. The rate at which resistors divide the voltage is equal to the ratio of the resistance value.
A typical wire is a metal with almost zero resistance. Therefore, the voltage across the wire in the circuit will be ‘0’.
If a portion of the wire is disconnected, it can be assumed that an infinite-sized resistor is connected to that location.
