Draw the circuit diagram of Wheatstone bridge. Under what condtion, no current flows through its galvanometer (balanced condition)?

What is cause of heat produced in a conductor when current flows through it?

Wheatstone bridge is said to be balanced, when no current flows through the.......

What is Wheatstone bridge? Deduce the condition for which Wheatstone bridge is balanced.

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: Potentiometer is the practical form of wheatstone bridge. Reason:In balanced position of wheatstone bridge, the galvanometer shows large deflection.

Derieve condition of a balanced wheatstone's bridge.
