The below Fig. shows the common emitter npn amplifier circuit. Note that a battery VBB is connected in the input circuit
Named after its inventor, a Shockley diode is a PNPN device having two terminals as shown in Fig. (i). This device
An optoisolator (also called optocoupler) is a device that uses light to couple a signal from its input (a photoemitter
There are a large number of applications of photo- diodes. However, we shall give two applications of photo-diodes by way
There are two important characteristics of photo- diode. (i) Reverse current-Illumination curve. The below Fig shows the graph between reverse
LEDs are often grouped to form seven-segment display. The below Fig. shows the front of a seven segment display. It
A LED that emits one colour when forward biased and another colour when reverse biased is called a multicolour LED.
1. Explain what is a pn junction? The contact surface between the layers of p-type and n-type semiconductor pieces plated
Actuators may be categorized as ‘direct acting’ or ‘reverse acting’ and some configurations are indicated in Below Figure. In a reverse acting actuator an increase
