In a meter bridge experiment the ratio
WebJun 8, 2024 · Key concept: Meter bridge: In case of meter bridge, the resistance wire AC is 100 cm long. Varying the position of tapping point B, bridge is balanced. If in balanced position of bridge AB = l, BC = (100 – l) so that Q/P= (100-l)/l. Also P/Q=R/S=>S= (100-l)/l R Webthis experiment. You can also do step 1 in the Wheatstone Bridge section. Background The Wheatstone Bridge circuit can be used to measure an unknown resistance in terms of three known resistances by adjusting one or more of the known resistors to obtain a zero signal (i.e. a \null" reading) on a meter. Such a measurement permits high precision ...

WebDec 6, 2024 · The plot of the variation of potential difference across a combination of three identical cells in series, versus current is as shown in the figure. What is the emf of each cell? (Delhi 2008) Answer: Total emf of three cells in series = P.D corresponding to zero current = 6V ∴ The emf of each cell = = 2V Question 2. WebMake sure that the pointer of the galvanometer deflects towards opposite directions when you make the contact between the jockey and the meter bridge's wire near end-A and end-B. 2) Choose the values of P and Q, and make sure that they are not equal. Calculate r = P/Q. 3) Put the plugs in the commutator to connect (w, y) and (x, z) terminals.
WebApr 3, 2024 · Hint: The ratio of resistances on the left end and right end of the given meter bridge will be equal to the ratio of the distance between the left end and right end and jockey. We will use this expression for the metre bridge to calculate the value of unknown resistance. Complete step by step answer: Given: The balancing length from the left end is Webthis experiment.
