HSC, Note, Physics 2nd Paper Static Electricity Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast [...] Math Solution of Static Electricity by Shah Jamal in Bangla Version, HSC, Math Solution, Physics 2nd Paper Math Solution of Static Electricity Static electricity is an excess of electric charge trapped on the surface of an object.

Michael Faraday is generally credited with the discovery of induction in 1831 though it may have been anticipated by the work of Francesco Zantedeschi in 1829. Around 1830 [...] Math Solution of Electromagnetic Induction & Alternating Current by Shah Jamal Math Solution of Electromagnetic Induction & Alternating Current Electromagnetic induction is the production of a potential difference (voltage) across a conductor when it is exposed to a varying magnetic field.

They are all the same kind of wavy disturbance that repeats itself over a distance called the wavelength. Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence [...] Math Solution of Electromagnetic Wave by Shah Jamal Math Solution of Electromagnetic Wave Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves.
