Four Iron metal rods of lengths 78 cm, 104 cm, 117 cm, and 169 cm are to be cut into parts of equal length. Each part must be as long as possible. What is the maximum number of pieces that can be cut? 
Detailed Solution for MPPGCL JE Electrical Mock Test - 5 - Question 9

Since each Iron rod must be cut into parts of equal length and 
each part must be as long as possible, so HCF should be 
taken. 
HCF of 78, 104, 117 and 169 = 13. 
No. of parts from 78cm. rod = 78 /13=6 
No. of parts from 104 cm. rod =104/13=8 
No. of parts from 117 cm. rod =117/ 13=9 
No. of parts from 169 cm. rod =169 /13=13 
Maximum no. of pieces = 6 + 8 + 9 + 13 = 36

A real inductor has resistance because it is composed of a coil of wire with nonzero resistivity. To measure the inductance of a coil, a student places it across a 12.0-V battery and measures a current of 0.72 A. The student then connects the coil to a 30.0-V (rms) 60 Hz generator and measures an rms current of 0.86 A. What is the inductance of the coil?
Detailed Solution for MPPGCL JE Electrical Mock Test - 5 - Question 11

The coil has an inductance and resistance. We can visualize the coil therefore as an inductor and resistor in series. When we connect the DC battery across the coil, we have therefore and LR circuit. The steady state current is just i0 = V/R – same as above. So

A capacitor used on 230 V AC Supply should have a peak voltage rating of-
Detailed Solution for MPPGCL JE Electrical Mock Test - 5 - Question 18
First, there is the voltage rating. The voltage rating on a capacitor is of course a maximum DC (i.e. a peak) rating. For 50/60Hz mains we're talking about a sinusoidal voltage waveform with an RMS value of for instance 230V, so the DC peak value of such a supply is Vrms⋅√2 or about 1.4 times this quoted value. If you're already dealing with a DC system, there is no math involved. The peak rating of your cap should be more than the peak DC voltage you expect over the device.

For longevity and nonlinear effects at high stresses, it is recommended to keep ample margin on these ratings, especially on the voltage rating. For 230VAC applications, even though typically you wouldn't expect more than about 325V peak over your lines, choose at least a 400V or better even a 450V capacitor. And yes, even when the manufacturer specifies survivability of the part at higher voltages. Survivability does not mean proper operation. It just means that it doesn't blow up and cause a mess.

Hence, the correct option is (A)

Detailed Solution for MPPGCL JE Electrical Mock Test - 5 - Question 19
Suppose +Q is the charge on one plate and –Q is charge on the second plate. Bring a rectangular slab made up of conducting material between the plates of the capacitor. The thickness of the slab must be less than the distance between the plates of the capacitor. When the electric field will be applied then polarization of molecules will be started. The polarization will take place in the same direction as that of the electric field. Consider a vector that must be polarized, name it as P. The polarization vector must be in the direction of the electric field Eo. Then this vector will start its functioning and will produce an electric field Ep in the opposite direction to that of Eo. The net electric field in the circuit is shown by the figure.

Hence, the correct option is (A)
