Working Principle of D.C Motor
A) An electric motor is a machine which changes electrical energy into mechanical energy.
B) When a current carrying conductor is placed in a magnetic field, it experience a mechanical force whose way is given by " Flemings Left hand rule" & magnitude is given by F= B.I.L Newton
C) When field magnets are excited and armature conductors are supplied with current from supply main, they experience a force tending to move the armature. Armature conductors under N-Pole are supposed to carry current in (crosses) and those under S-Pole to carry current out (dots).
Two flawlessly conducting spheres are in an evacuated region of space. One is at a potential of 12 volts as well as the other is at a potential of 15 volts. A free electron is rele
A cab driver in a hurry is sitting at a red light. When the light turns green she rapidly accelerates for 3.50 s at 6.80 m/s 2 . The next light is still red. She then slams on
Why is it that the frequency of light remains the constant as it undergoes refraction at the interface of two material mediums? Ans) If frequencies are dissimilar in different m
Does sunlight reflected off a mirror enhance the temperature of the sun-rays? A standard planar mirror will not enhance the energy contained in the rays that reflect off it. In

Electric current may be expressed in which one of the following units? a) coulombs/volt b) joules/coulomb c) coulombs/second d)
A record player's needle is 6.5 cm from the center of a 45-rpm record. Calculate velocity of the needle?
A train consists of a 4300-kg locomotive pulling two loaded boxcars. The first boxcar has a mass of 12,700 kg and the second has a mass of 16,300 kg. Presume that the boxcar wheels
Ball A, with a mass of 0.20 kg, strikes ball B, with a mass of 0.30 kg. The initial velocity of ball A is 0.95 m/s. Ball B is initially at rest. What are the final speed an
