application to switching circuits

. The magnitude of the current depended on the strength of the magnet and also on the magnitude of their relative velocity. Similar results were seen when the magnet is replaced by as coil connected to a battery. Even without physically moving the coils a current was shown in the galvanometer only ..

Let us refer to a circuit consisting of two switches p and q connected in parallel with a lamp and battery as shown in figure. In this case, the lamp will glow if and only if at least one of the switches is closed. In binary language we say the switch will..

Place some pins in a box just below the nail and switch on the key. The pins readily jump towards the nail. This shows that the nail has acquired magnetism. That is, the nail is an electromagnet. Switch off the circuit and observe. The pins fall into the b..

An 'AND' gate is a Boolean function with two input variables x 1 , x 2 , defined by f(x 1 , x 2 ) = x 1 , x 2 where x 1 , x 2 {0, 1} The input-output table for 'AND' gate is given below, which is similar to Table 3 (A circuit with two switches connected in seri..

. The depolarisation action proceeds slowly. When current is drawn continuously, a partial polarisation therefore sets in, because of which the current falls. So the circuit is switched off till the hydrogen gas escapes. It is ready for use after sometime. The Leclanche cell is ..

The 'modem' is a contraction of the term modulator-demodulator. It is a conversion that facilitates the transmission and reception of the data over the public switched telephone network (PSTN). The data of interest may be digital signals generated by computers or service providers. In suc..

Electric bell suspended inside an airtight glass bell jar An electric bell is suspended inside an airtight glass bell jar connected with a vacuum pump. As the electric bell circuit is completed, the sound is heard. Now if the air is slowly removed from the bell jar by using a vacuum p..

. Some of the important applications of eddy currents are: Electromagnetic damping, induction furnace, electromagnetic brakes, induction motor speedometers and in diathermy i.e., deep heat treatment of parts of human body. Some of the undesirable effects of eddy currents are that they opp..

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..
