Semiconductors are those substances whose electrical conductivity lies in between conductors and insulators. In terms of energy band, the valence band is almost filled and conduction band is almost empty. Further, the energy gap between valence band and conduction band is very small. The semiconductor has filled valence band, empty conduction band, and small energy gap … Read more
A subtractor is a digital logic circuit in electronics that performs the operation of subtraction of two number. Subtractors are classified into two types: half subtractor and full subtractor. The half subtractor (HS) circuit has two inputs: A and B, which subtract two input binary digits and generate two binary outputs i.e. borrow and difference. Truth table … Read more
An Adder is a digital logic circuit in electronics that performs the operation of additions of two number. Adders are classified into two types: half adder and full adder. The full adder (FA) circuit has three inputs: A, B and Cin, which add three input binary digits and generate two binary outputs i.e. carry and sum. Let’s see an … Read more
An Adder is a digital logic circuit in electronics that performs the operation of additions of two number. Adders are classified into two types: half adder and full adder. The half adder (HA) circuit has two inputs: A and B, which add two input binary digits and generate two binary outputs i.e. carry and sum. Let’s see an addition … Read more
As we know that the 8085 microprocessor is an 8-bit microprocessor. So, a total of 256 instruction codes can be generated using 8-bit combinations. But out of 256 instruction codes, only 246 instruction codes are defined by INTEL Corporation for 8085 microprocessor. Each defined instruction code performs a unique task. These instruction codes are called … Read more
In previous articles, we discussed different types of single-phase induction motors such as Split phase induction motor, Capacitor-start inductor motor, Capacitor-start capacitor-run induction motor, and Shaded pole induction motor. In this article, we will see another type of single phase motor i.e. Permanent Split Capacitor Induction Motor. It is also known as Permanent Split Capacitor Motor or … Read more
The distribution of current over the entire cross-section of the conductor is uniform in case of a DC system. But there is an unequal distribution of current over the entire cross-section of the conductor in case of AC system. Here what Skin Effect arises. What is Skin Effect (SE)? When an AC Current flows through a conductor, … Read more
In this article, we will learn Proximity effect that occur in conductors. What is Proximity Effect? Suppose two or more conductors carrying AC current are placed near each other. Each conductor is producing its varying magnetic field. When this varying magnetic field is linked with other current carrying conductors then the distribution of current in each … Read more
A Capacitor Start Capacitor Run Induction Motor is a single phase motor consists of a stator and a single-cage rotor. The stator has two windings i.e. main winding and an auxiliary winding. The auxiliary winding is also known as starting winding. In construction, these two windings are placed 90° apart in space. This motor has … Read more
Statement Blondel’s theorem states that if a network is supplied through P conductors, the total power is measured by adding the readings of P wattmeters so arranged that a current element of a wattmeter is in each line and the corresponding voltage element is connected between that line and a common point. Note: If the … Read more
