Draw the circuit digram of a Wheatstone bridge and write down its balance condition .

Draw Wheatstone bridge circuit and write down the balancing condition of it. In a meter bridge the balance point is found to be at 40 cm from one end when the resistor at the end is 10 Omega . Find the resistance at the other side. If the galvanometer and the cell are interchanged at the balance condiotion, would it affect the current through the galvanometer?

Draw the circuit diagram of an OR gate using p-n junction diodes. Write down the table ofan OR gate.

Statement I : If the resistance of the first two arms P and Q of a balanced Wheatstone bridge are exchanged , the balanced condition is not disturbed . Statement II : The balanced condition of a Wheatstone bridge is independent of the resistance of the galvanometer used .
