How will you convert a galvanometer of resistance 12 ohms showing full scale deflection for a current of 3 milli ampere to
(i) Ammeter of range o to 6 Ampere
(ii) Voltmeter of range 0 to 18V.
An infinitely long straight conductor 'XY' is carrying a current of 5 Ampere. An electron moving with a speed of 10^5 m/s parallel to the conductor in air from A to B. Calculate the magnitude of force experienced by the electron and direction of force.
Pls help. Ur help will be greatly...
