Two resistors are connected in series and then in parallel in an electric circuit what effect will it have on the reading of voltmeter and ammeter in both the cases? Voltmeter is connected across the two resistors

When taking these circuits into consideration we must first make reference to the laws governing them. I assume you’re familiar will ohms law, Kirchhoff’s voltage law etc.
Now, if we have a voltage source of 12volts along With the two 2 ohm resistors in a series circuit, then dividing the voltage by the resistance will give us 3 amps around the circuit. Owing to the fact that the resistors would add up and form a total resistance of 4ohms. And the volt meter would read 6volts across each resistor. While the current remains constants.
On the other hand, if we were to use these same parameters in a parallel circuit then automatically the rules governing the circuit changes. The voltage now becomes constant across every branch. So placing he voltmeter at any branch would read 12v. While the current becomes variable. Owing to the fact that both resistors are of same value then we can say that there would be 6amps flowing through each branch. So your ammeter readings would be double as compared to the series circuit.
