Construction of TRIAC ( triode for alternating current)
The TRIAC stands for triode for alternating current. It is another thyristor family device which is used extensively for the control of power in A.C. circuits. The TRIAC is bidirectional device and when in operation, it is
Advantages and disadvantages of TRIAC
There are some advantages of TRIAC which are given below, The TRIAC need single fuse for protection. It can be triggered with positive or negative polarities of gate pulses. A safe breakdown in either direction is possible
Difference between SCR and TRIAC
Following are main difference between SCR (Silicon controlled rectifier)and TRIAC (Triode for alternating current) : SCR TRIAC SCR stands for silicon controlled rectifier. TRIAC stands for triode for alternating current. The SCR is unidirectional device. The TRIAC is

Difference between time domain and frequency domain
There is the difference between time domain and frequency domain are given below, Time domain Frequency domain The advantage is that, they are relatively fast and requires less memory than inverting the Helmholtz operator. The advantage is
Construction of silicon controller rectifier (SCR)
The basic construction of silicon controlled rectifier (SCR) is shown in above fig. It is made up of silicon and its operation as a rectifier can be controlled, hence the name given as silicon controlled rectifier. The
Construction of ramp type DVM (digital voltmeter)
The ramp type DVM (digital voltmeter) uses a linear ramp or staircase ramp technique. The staircase ramp technique is a simpler version of linear ramp technique. The block diagram of ramp type DVM is shown in above
Advantages and disadvantages of silicon controlled rectifier (SCR)
There are some advantages of silicon controlled rectifier (SCR) which are given below, The silicon controlled rectifier (SCR) can handle large voltage , current and power. It can be protected with the help of fuse. It is
Construction of successive approximation type DVM (Digital voltmeter)
The successive approximation type DVM is special type of potentiometric DVM in which a digital divider is used in the place of linear divider. The servomotor replaced by electromagnetic logic. The comparator compares the output of
