What will happen if the upper outlet of the condenser is connected to the tap instead of the lower outlet?

Answer the following question: What will happen of an ammeter of high resistance is connected in the circuit to measure the current?

Condensers of capacities 5 F and 10 F are connected in parallel in a circuit with a cell of e.m.f. 2V. What should be the capacity of the condenser to be connected in series with parallel combination of the condensers to get 1 C charge to flow in the circuit ?

Oral Work : What will happen when only upper part of liquid is heated?

A circular loop of radius 'r' of conducting wire connected with a Voltage source of zero internal resistance produces a magnetic field 'B' at its centre. If instead, a circular loop of radius '2r' made of same material, having the same cross section is connected to the same voltage source, what will be the magnetic field at its centre?

Questions based on paragraph Study the following activity and answer the questions. Take two aluminium channels of different lengths. Place the lower ends of the channels on the floor and hold their upper ends at the same height. Now take two balls of the same size and weight and release them from the top end of the channels. They will roll down and cover the same distance. What is the form of the eventual total energy of the balls?

Answer the following questions: A tapping vessel opens in a tank like container that is tapering on the lower side .The tank has an outlet for water on the upper side a water inlet on the lower side. Finely ground ore is released in the tank. A forceful jet of water is introduced in the tank from lower side and gangue particles and pure ore are separated by this method. The above description is of which gravitation separation method ?

A block of mass m_(2) is placed on a horizontal table and another block of mass m_(1) is placed on top is it. An increasing horizontal force F = alpha t is exerted on the upper block but the lowwer block never moves as a result. If the coefficient of friction between the blocks is mu_(1) coefficient of friction between the blocks is mu_(1) and that between the lower block and the table is mu_(2), then what is the maximum possible value of mu_(1)//mu_(2) ?

If the plates of a charged capacitor are suddenly connected to each other by a wire, what will happen?
