Fleming's right hand rule

The direction of dynamically induced emf can be identified by this rule.Hold the thumb,forefinger and middle finger of the right hand at the right angles to each other as shown in the photo such that the forefinger is in the direction of the motion of the conductor, then the middle finger indicates the direction of emf induced. i.e.towards the observer or away from the observer.

Fleming's left hand rule

Fleming's left hand rule The direction of force produced on a current-carrying cunductor placed in magnetic field can be determined by this rule. as shown in photo hold the thumb,forefinger and middle finger of the left hand mutually at right angles to each other., such that the forefinger is in the direction of current flow in the cunductor; then the thumb indicates the direction of motion of the conductor.

Disc number calculator

Disc number calculator Normally the disc capacitors does not contains it's original value. but we can calculate it from the number printed on disc. They have three numbers the third number indicates the number of zero to be added, Example = disc no:-104 here the last number = 4 so add four zero to 10 = 100000 give point on three decimal places = 100nf
