equivalent circuits

Two combinatorial circuits, each having inputs x 1 , x 2 , x 3 , x 4 ,x n and a single output are said to be equivalent if their input/output tables are identica..

At most places, the household electric power is supplied at 220V, 50H. If such a source is directly connected to the tube, the tube will be damaged. To reduce the current, a choke coil is connected in series with the tube - representing the tube by a resistance and the choke coil by an ideal i..

Resistors in Series and in Parallel - When resistors, can be connected in such a way that the same current flows in them, then they are said to be connected in series. The resistors are said to be connected in parallel if the potential difference is the same across each resistor. For any combinatio..

Let us consider two resistances 'R 1 ' and 'R 2 ' connected in series. A battery of 'V' volts is applied to the ends of this series combination. Let us name the potential difference across R 1 as V 1 , and that across R 2 as V 2 . Since 'V' represents energy, according to the law of conservation of..

Law of Combination of Resistors in Series - Let us consider two resistances 'R 1 ' and 'R 2 ' connected in series. A battery of 'V' volts is applied to the ends of this series combination. Let us name the potential difference across R 1 as V 1 , and that across R 2 as V 2 . Since 'V' represents ene..

>When the resistances are connected in parallel the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of the individual resistances. The amount of heat generated in a conductor of resistance 'R', when current 'I' flows through it in a given time 't', is given ..

Ag dissolves into the solution and the released electron flow towards the positive end of the external source. In this process one electron circulates for the deposition of every silver atom on the cathode. Faraday's laws of electrolysis: (a) The mass of substance (m) deposited at the cathode (or d..

Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point. Electrical potential is a scalar quantity. The potential diff..

Electrolysis of copper sulphate solution It is found that copper is removed from the anode and is deposited on the cathode. Due to ionization, the CuSO 4 solution is dissociated. ..
