Answer 1

Both the 10 ohm resistors have a voltage of 0.5 units , since 2 V is given for 20 ohm resistor .

Answer 2

Hey dear,

[Refer to the image attachment for circuit diagram.]

● Explaination -
For parallel combination, effective resistance is -
R = 10×10 / (10+10)
R = 5 ohm

Equivalent resistance across circuit is -
R' = 20 + 5
R' = 25 ohm

Current in circuit is -
I = 2.5/25
I = 0.1 A

Voltage across 20 ohm resistor,
V = 20×0.1
V = 2 V

Therefore, ammeter will read 0.1 A and voltmeter will read 2 V across 20 ohm resistor.

Hope this helps...
