Electronic Devices and Circuits Understanding Diode
A one of the basic circuit element with numerous applications. Diode is a semiconductor device which allows the flow of current only in one direction and stops the flow of the diode in the opposite direction. Due to this peculiar behaviour of diode it is used in making power supplies especially mobile phone charges and adaptors of laptops and etc. Ideal Diode: An ideal diode is shown in the figure above. An ideal diode behaves as a short circuit when operated in forward direction ( forward biased region) and acts as an open circuit when operated in reverse direction ( reverse biasing region). An ideal diode has zero voltage drop at its terminals. In the figure a above it can be clearly see that when positive terminal of the battery is connected with the positive terminal of the diode. in this case the diode is short circuited and current will flow through the circuit and bulb will glow In figure b negative terminal of the battery is connected is with the positive terminal of the d...
