Video by Prof ShrenikThis video contains an answer to a very basic and Simple question...Why there is No/Zero deflection in galvanometer for balanced conditi...
There is no material with zero deflection in the world. Every thing deflects, to different degrees. The best possible way to prevent a bracket from failure is to design it for the task it must do.
Moving forward, it's essential to keep these visual contexts in mind when discussing Zero Deflection Industrial Practices.
(2) On decreasing the current through the potentiometer wire, the potential gradient along the wire will decrease. Hence, the position of zero deflection will occur at a longer length.Write two possible causes for one sided deflection in a potentiometer experiment.
If Potential across AJ (V) is equal to emf E then no current will flow in the galvanometer circuit this condition to known as null deflection position, length AJ (x) is known as balancing length.As a result position of zero deflection will occur at a longer length. Hence option 2) is correct.
zero deflection is impossible for obvious reasons. Tell the door manufacturer that he's out to lunch and there has to be some form of allowable deflection. That would be like us telling him that his door can weigh zero pounds or else the framing below could collapse.
Practice Papers.Complete step by step solution: In the question it is mentioned that the galvanometer shows zero deflection. This means that the current through both the loops are equal. Let us divide the circuit in two loops, ABEF and BCDE, as shown in the figure.
The potentiometer is based on the zero deflection method . A potentiometer is an instrument used to measure the electromotive force (emf) of a cell or to compare the emf of two cells without drawing any current from the cells.
