voltage amplifier meaning in Hindi

Examples

1. It is measured by connecting the electrodes to a voltage amplifier.
2. Voltage amplifiers and current amplifiers have different topologies for best noise characteristics.
3. Often this circuit is selected when a voltage amplifier is wanted at the output.
4. Voltage amplifier valves not operating at high power are not affected in this way.
5. Practically all commercial audio amplifiers are voltage amplifiers.
6. Op-amps are differential voltage amplifiers with very high gain ( sometimes modeled as infinite gain ).
7. A feedback voltage amplifier using an op amp with finite gain but infinite input impedances and zero output impedance.
8. A simple example of the use of feedback is the op-amp voltage amplifier shown in the figure.
9. The common base circuit stops behaving like a voltage amplifier and behaves like a current follower, as discussed next.
10. So, for example, an op amp ( voltage amplifier ) can be arranged to make a current amplifier instead.
