Question

Four resistances of 3ohm,3ohm,3ohm, 4ohm respectively are used to form a wheatstones bridge.the 4 ohm resistance is short circuited with resistance r in order to get a balanced bridge. the value of r will be

Answer 1

Obviously, r = 3 ohm .

Because according to question, Circuit is a balanced wheatstone bridge .

So, r = 3 Ohm .

Hope it's helpful to you.
