Extrinsic semiconductors
Semiconductors can be broadly classified into Intrinsic and Extrinsic Semiconductors. Intrinsic Semiconductors start conducting at temperatures above the room temperature, developing important electronic devices using these can pose a problem. This led to…
Classification of electric materials
Materials in electronics can be classified as electrotechnical, constructional and special. Electrotechnical materials are classified by four groups: Conductors Semiconductors Isolators Magnetic materials. Electrotechnical materials are those which have some specific…
Synchronous Machine
Synchronous Machine constitutes of both synchronous motors as well as synchronous generators. An AC system has some advantages over DC system. Therefore, the AC system is exclusively used for generation, transmission…
DC Machine
The DC machine can be classified into two types namely DC motors as well as DC generators. Most of the DC machines are equivalent to AC machines because they include AC currents as…
Alternating Current (AC) Home Wiring
Homes in North America typically are powered with both 120-volt and 240-volt alternating current (AC) electricity. (Because of voltage variations, they are also listed as 110-120 VAC and 220-240 VAC).…
Circuit Analysis of 3 Phase System – Balanced Condition
The electrical system is of two types i.e., the single phase system and the three phase system. The single phase system has only one phase wire and one return wire…
Power Triangle and Power Factor
Electrical power consumed in an AC circuit can be represented by the three sides of a right angled triangle, known commonly as a power triangle We saw in our tutorial…
RMS Voltage of AC Waveform
An alternating waveform or AC waveform, which is associated with the AC current, is a periodic waveform that alternates between the positive and the negative values. Sine or Sinusoidal wave…
AC Circuits
Alternating current Direct current (DC) circuits involve current flowing in one direction. In alternating current (AC) circuits, instead of a constant voltage supplied by a battery, the voltage oscillates in…
Maximum Power Transfer Theorem
Maximum Power Transfer Theorem can be stated as – A resistive load, being connected to a DC network, receives maximum power when the load resistance is equal to the internal resistance…
