Flemings right hand rule:
When a straight wire is moved through a magnetic field, an emf is induced in it, in the manner of the coil and magnet experiment. Once again, lines of flux are being cut by a conductor and if the wire forms part of a closed circuit, a current will flow. The same effect is observed if the wire is stationary and the magnetic field moves. The direction of the induced emf may be determined by Fleming's Right Hand Rule.
The thumb, first finger and second finger of the right hand are held at right angles to each other, then:
• With the thuMb pointing in the direction of the conductor movement.• With the First finger pointing in the direction of the magnetic field (N to S).• Then the seCond finger points in the direction of conventional current flow and thus indicates the direction of the induced voltage.
Draw a circuit diagram of a common emitter amplifier by using n-p-n transistor. Show input and output voltages graphically. The current gain for common emitter amplifier is 59.
in a uniform electric field, the potential is 10v at the origin and 8v at each of the points (1,0,0),(0,1,0) and (0,0,1).Find the potential at the point (1,1,1).
A small ball with a mass of 60.0 g is loaded into a spring gun, compressing the spring by 12.0 cm. When the trigger is pressed the ball emerges horizontally from the barrel ata hei
