Question

Find the ratio of the readings of V2:V1​

Answer 1

E net =6V

I ohm and 2 ohm resistor are in series

R net = 1+2 =3 ohm

I net = E /R

I net = 6/ 3 =2 A

We know that in series combination the current flowing through both the resistors is the same

V1 = I net × R1

V 1= 2×1 =2 V

V 1= 2 V

V2 = I net × R 2

V 2 = 2× 2

V 2 = 4 V

Ratio of V2 : V1

V 2/ V 1 = 4/2

V2 /V 1 =2/1

Answer 2

Answer:

1:1

Explanation:

We know that, the resistance of a voltmeter should be ideally infinite. This is because maximum amount of current should pass through the circuit component. This will ensure that we don't alter the voltage across that component after connecting a voltmeter.                                                                                                

                                  AND WE ALSO KNOW THAT

In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component.

SO THE VOLTAGE RATIO WILL BE 1:1
