Three Phase Inverter: The topology of a three-phase inverter consists of 3 legs; each leg includes a switch in either…
MAGNETISM There are several relationships between electricity and magnetism. We will explore them one by one. The first relationship we…
In figures below, npn transistors are shown. Supply voltage polarities are reversed for pnp transistors.
In the interest of simplicity and economy, it is desirable that transistor circuit should have a single source of supply—the…
The collector current in a transistor changes rapidly when (i) the temperature changes, (ii) the transistor is replaced by another…
In Figure, the base resistor RB is connected to the collector rather than to VCC, as it was in the base…
If an emitter resistor is added to the base-bias circuit, the result is emitter-feedback bias, as shown in Figure. The…
This method of biasing is common in switching circuits. Figure shows a base-biased transistor. The analysis of this circuit for the…
Emitter bias provides excellent bias stability in spite of changes in β or temperature. It uses both a positive and a…
