hen the coil passes the brush, its current changes direction. Ideally the current changes ……… in the coil. This ideal situation provides a smooth transfer of current. But due to coil ……… (the current reversal takes some time to take place 18.46 A                *Linearly-resistanceNon Linearly- Inductancelinearly- InductanceLinearly- Capacitive

What is the purpose of the brushes in a DC generator?a.To convert AC output to DCb.To maintain electrical contact with the commutatorc.To supply power to the field windingd.To reverse the direction of current flow in the armature windings

What do you WONDER about the behaviour of the current-carrying coil?

he …… creates flux which will create an emf that cancels out the induced emf in the coil undergoing commutation        *Pole shoeInterpolesCommutatorBrushes

n a coil of resistance 100  a current is induced by changing the magneticflux through it. The variation of current with time is as shown in the figure. Themagnitude of change in flux through coil is(a) 200 Wb (b) 275 Wb (c) 225 Wb (d) 250 Wb

​the diagram below shows a current carrying wire placed inside a magnetic coil.State the difference it would make if the wire is replaced with a coil with more turns.Secondly the direction of current is reversed and the poles of the magnets are also reversed.Describe your answer in 25 to 35 words.B
