AC Circuit with Pure Capacitance only
Therefore the non-resistive of a coil to a.c. due to the varying magnetic field is called capacitive reactance Xc. Unit of Xc is also Ohm The current leads the EMF by 90 o and the phasor diagram is: For DC, Xc becomes infinite and hence, capacitance block DC flowing through i..

If the current flows always in the same direction, it is called 'direct current'. Direction current is represented as DC or dc. The current derived from a cell or a battery is direct current - since it is unidirectional. The positive and negative terminals are fixed. If th..

When the current flows in the same direction it is called 'direct current' or DC The current derived from a cell or battery is unidirectional. So it is a DC source It is represented in an electrical circuit as The voltage V/s time graph for a DC sou..Summary
.c. It is represented by I r m s , I e f f or I v . It can be shown that All a.c. instruments measure virtual values of a.c. The behavior of an ohmic resistance R in a.c. circuit is the same as in d.c. circuit. Through alternating EMF and alternating current are in sam..
Main Parts of the AC Generator
>As the armature rotates about an axis perpendicular to the magnetic field, it keeps on changing its relative orientation with respect to the field Thus the flux keeps on changing continuously with time This change in magnetic flux induces an emf If the outer terminals of the armature are connected..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Tutor helped me on every question and help me when i was confused. Thank you Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutors are pleasant and great to work with, they were very patient and explained everything that is simple to follow. I love working with them. - John Coakley
