WebFeb 13, 2024 · The value of shunt is chosen in such a way that only a desirable amount of current I g flows through the galvanometer and remaining current (I–I g) flows through the shunt. Since, shunt and galvanometer are in parallel combination, $\therefore $ p.d. across shunt (S) = p.d. across galvanometer (G) Or, (I–I g).S = I g G Webfrom equation (E 6.1) we get I g = k θ Combining equations (E 6.2) and (E 6.3) we get E R + G = k θ On keeping both the keys K 1 and K 2 closed and by adjusting the value of shunt …

Using Ampere’s circuital law, obtain an expression for the magnetic field along the axis of a current carrying solenoid of length l and having N number of turns. WebA DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to … WebThis high resistance is often called a multiplier. The formula of the high resistance is. R =(V – IGRG)/ IG. Here, V= voltage provided. R= the resistance of the multiplier. IG= the current of the galvanometer. RG= the resistance of the galvanometer. IGRG= the maximum voltage the galvanometer can handle. chemical origins of unburnt hydrocarbons
