POTENTIOMETER EXPERIMENT/ K12 CBSE PHYSICS

February 11, 2022

POTENTIOMETER EXPERIMENT/K12 CBSE PHYSICS COMPARISON OF EMF OF TWO CELLS: EXPERIMENTAL SET UP : CIRCUIT DIAGRAM: CONDITIONS: SIMPLE CIRCUIT DIAGRAM: DOUBLE POLE DOUBLE THROW SWITCH CONNECTIONS : POTENTIAL GRADIENT : For better outcomes,utilize newly pre-arranged(freshly prepared) cell in any case, the polarization impact will happen which is segregating boundaries foster a connection point among cathode and electrolyte. The sensitivity of the potentiometer relies upon a potential gradient (K).If the potential gradient is little then the potentiometer is supposed to be more precise and delicate. PROCEDURE: This is the least complex circuit and every one of the connections are made as displayed previously. Connect the positive terminals of the auxiliary battery and primary cells to point A of the potentiometer (zero point). To actually look at the rightness(correctness) of the circuit,the pencil jockey is pressed close to the end A and B of the potentiometer.If the gal...

NEET PHYSICS TEST ARRANGEMENT: QUESTION: A capillary tube of radius 'r' is immersed in water and the water rises it to a height h.The mass of the water in the capillary tube is 5 g. Another capillary tube of radius '2r' is immersed in water.The mass of the water that will rise in the tube is; [A]. 2.5 g [B]. 5.0 g [C]. 10.0 g [D]. 20.0 g ANSWER: ANSWER - [C] SOLUTION: CAPILLARY RISE: A capillary tube (glass tube) of radius 'r 'is dipped in water, the surface pulls the capillary walls in downward direction. Capillary walls pull the surface in upward direction. By the way the water in the tube will rise above the adjacent liquid level till the forces get balanced. This rises what we called it as capillary rise WHAT ARE THE TWO FORCES ACTING AT EQUILIBRIUM? 1. First one is the weight of the water column, acting downwards. ...

NEET | JEE | Preliminary Physics: An instructive stage began during the pandemic time frame and that was an ideal opportunity to persuade the understudies and it is by all accounts a test for guardians, instructors, teachers during that pandemic. Thus, we began our site to unite information, asset sand exercises to assist understudies as they with investigating, learn and share the information during the difficult stretch. We considered giving opportune methodology especially with the goal that it might offer nonstop and individual help to understudies. We have put our time and assets in fostering the substance at most consideration despite everything we are raising our substance in light of understudy's capacity, understudy focused exertion to adapt up to the subject without even a trace of an educator. We have helped countless understudy around 150 nations to set off their improvement exercises with the expect to turn into the top to bottom information. The right subsidizing for a brand is a vital financial and counsel related help that assumes a significant part for them to push ahead in a worldwide scale.
