Hi
Can somebody please explain me something
1) Can u give me some e.g.s of application of left hand rule and right hand rules.......pls i don't understand it where to use which one............?
2)In transistor IB+IC=IE So my teacher told that the IC current is amplified how is that???
3)IN diodes what is full wave/half wave rectifiacation.....why and where and when its used......................??
4)what is potential divider,and time delay circuit...............??
I have asked too many doubts.......... Thanks a lot............
2.
IE and IC are connected to the same circuit, the small current from IB can be used to control the larger circuit, that is the circuit which goes through IE and IC, the sum of the current flowing through that larger circuit would be the output at IE, that is IB + IC. Notice that you are amplifying the very small current, that is, IB in this case ... The transistor can also be used as a switch to turn on a low-power electrical component, such as a logic gate.
4. A capacitor can be found in a time delay circuit. It is a component that charges up when a current flows through, the current stored can be used to power another device. As it takes time for the capacitor to charge up, the arrangement is hence called a time delay curcuit.
