The batteries are available with some specific terminal voltages. e.g. 1.5V, 6 V, 12 V, 24 V, 48 V etc. If we want to have some terminal voltage other than these standard ones, then series or parallel combination of the batteries should be done. One more reason for connecting the batteries in series or parallel […]

The transistor circuit which involves more than one stage (or) multiple stages of amplification is called a multistage amplifier or cascaded amplifier. The block schematic of a multistage amplifier is shown in figure below. The overall gain of a multistage amplifier is the product of gain of individual stages.
