As it is obtained by rubbing two substance such as glass and silk it is also called frictional electricity.  \n5) What is current electricity ?  \n􀀁 Current electricity means the electricity in motion the effects of which are due to the flow of electrons in a conductor.  \n6) What are the types of current electricity ?  \n􀀁 There are two types :- (1) Direct current and (2) Alternating current.  \n7) What are the different methods of producing electricity ? Give examples.  \n􀀁 The methods are –  \ni) By means of frictions-Static electricity is produced.  \nii) By means of chemical action in cells and batteries.  \niii) By means of mechanical driving-Generator produces electricity in two dissimilar methods.  \niv) By means of heat – Thermal electricity is produced.  \nv) By means of lighting effect – Electricity is produced in photo electric cell.  \n8) Explain the difference between direct and alternating current?  \n􀀁 Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit.  \n􀀁 Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidal, the circuit is known as an alternating current circuit.  \n9) Where is D.C. used ?  \n􀀁 (1)Battery charging,(2)Electroplating,(3)Electrolysis,(4) Relays,(5) Traction motors,(6) Cinema projector.  \n10) Where is A.C. used ?  \n􀀁 (1)House hold appliances,(2) Fan,(3) Refrigerators,(4)Power driving motors. (5)Radio and T. V. Set etc.  \n11) What is active, reactive, apparent & complex power?  \n􀀁  I)  Active power: It is the actual power that is delivered to the load such as transformer, induction motors, generators, etc and dissipated in the circuit. It is denoted by P & its unit is watts W.  \n􀀁  II) Reactive Power: The powers that continuously bounce back and forth between source and load is known as reactive power. It is denoted by Q & its unit is VAR voltage-ampere reactive.  \n􀀁  III) Apparent Power: It is the product of voltage & current without referencing the phase difference between them. It is a combination of active power & reactive power. It is denoted by S & its unit Volt-Ampere, VA.  \n􀀁  III) Complex power: it is the product of voltage & current with reference to the phase difference between them. it is the complex sum or vector sum of the active power & reactive power. It is denoted by S & measure in VAR.  \n12) What is a leading & lagging power factor & how can you improve it? State the methods of power factor correction?  \n􀀁 The cosine of the angle between voltage & current is called the power factor. If the current leads the voltage, it causes a leading power factor. If the current lags voltage the power factor is lagging.  \nMost loads are inductive that causes a lagging power factor. Thus these following methods are used for p.f correction (to nullify the lagging current):-  \ni)  Static Capacitor  \n􀀁 The capacitor helps in providing a leading current that eliminates the lagging component of current & improves the power factor  \nii)  Synchronous Condenser  \n􀀁 It is an over-excited synchronous motor with no load that also provides a leading power factor.  \niii)  Phase Advancer  \n􀀁 Phase advancer is a simple AC exciter which is connected on the mai","cbCaijKMAXYVYNS0","https://ap.wps.com/l/cbCaijKMAXYVYNS0","pdf",401493,43,"English","# Electrical Interview Questions\n## Fundamentals of electricity\n## DC and AC concepts\n## Power in electrical systems\n## Power factor and correction\n## Circuit types","[{\"question\":\"What is the difference between static electricity and current electricity?\",\"answer\":\"Static electricity is electricity at rest, produced by electrostatic effects such as rubbing.
