Question

find the value of 'I'​

Answer 1

Answer:

0.5 A

Explanation:

It is wheetstone bridge you can remove 5 ohm in middle .

It is quite simple now 5 + 15 = 20 ohms in series above and down , so two resistance of 20 ohm in parallel . there net will be 20/2 = 10 ohm . And this 10 ohm in series with other 10 ohm .

So net resistance = 10 + 10 = 20 ohms

So current = V / R = 10 / 20 = 0.5 A
