2N3906
2N3906 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at the ground and will be opened (Reverse biased) when a signal is provided to the base pin.

The 2N3906 transistor is commonly used as a switching device. When used as a switch, it can be operated in a saturation region and cut-off region. In the PNP transistor, by default, it’s in ON state, but not to be said perfectly ON until the base pin is not grounded. If we provide ground to the base pin then the transistor will be in reverse biased and said to be turned ON. If supply is provided to the base pin it stops conducting current between emitter and collector and said to be in an OFF state. For the protection of the transistor, a resistance added in series with it.
