How transistor behaves as a switch?

One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off. When base voltage is present, the switch is on.

Which transistor is better PNP or NPN Why?

As the electrons have higher or faster mobility than holes, the conductivity also more. For this reason, NPN transistors are more preferable than PNP transistors because the NPN transistor provides more conductivity.

Is PNP a transistor?

The PNP transistor is a type of transistor in which one n-type material is doped with two p-type materials. When a small current flow through the base of the PNP transistor, it turns on. The current in a PNP transistor flows from the emitter to the collector.

Is PNP normally open?

PNP – (PNP transistor) NO – normally opened, that means there is no voltage on the output while the sensor is not actuated (see picture, PNP sensor output connector is no. 4).
