Q6.A solid iron cylinder is placed in a region containing a uniform magnetic field such that the cylinder axis is parallel to the magnetic field direction. The magnetic field lines inside the cylinder will
Answer : Option AExplaination / Solution:
Flux always chooses less reluctance path. So flux tried to flow inside the conductor and closer to the axis of the cylinder.
Q7.The slope and level detector circuit in a CRO has a delay of 100 ns. The start-stop sweep generator has a response time of 50 ns. In order to display correctly, a delay line of
Answer : Option AExplaination / Solution:
The delay line should be inverted in VDP (Y-channel) only.
Q8.The load shown in the figure is supplied by a 400 V (line to line) 3-phase source (RYB
sequence). The load is balanced and inductive, drawing 3464 VA. When the switch S is in
position N, the three watt-meters W1, W2 and W3 read 577.35 W each. If the switch is moved to
position Y, the readings of the watt-meters in watts will be
