Hence deduce the expression for its time period. (b) A compass needle, free to turn in a vertical plane orients itself with its axis vertical at a certain place on the earth. (ii) angle of dip at the place. (a) Draw a labelled diagram of a moving coil galvanometer. Describe briefly its principle and working.
6 de dic. de 2018 · State the principle of an ac generator and explain its working with the help of a labelled diagram. Obtain the expression for the emf induced in a coil having N turns each of cross-sectional area A, rotating with a constant angular speed ‘ ω ’ in a magnetic field vector B, directed perpendicular to the axis of rotation.
Draw a labelled diagram of a moving coil galvanometer and explain its working. What is the function of radial magnetic field inside the coil? State the underlying principle of working of a moving coil galvanometer. Write two reasons why a galvanometer can not be used as such to measure current in a given circuit.
The coil pack wiring diagram provides a visual representation of how the ignition coils are connected to the vehicle’s electrical system. It shows the arrangement of the primary and secondary windings, as well as the connections to the battery, ignition switch, and other components. By understanding this diagram, automotive technicians can ...
A soft iron cylindrical core makes the field radial and strong. Moving coil galvanometer. Working: The coil rotates due to a torque acting on it as the current flows through it. The torque acting on the current-carrying coil is τ = NIAB sinθ. Here θ = 90° as the field is radial. ∴ τ = NIAB.
5 de oct. de 2018 · It works on the principle of electromagnetic induction, i.e. when a coil continuously rotates in a magnetic field, the magnetic flux associated with it keeps on changing; thus an emf is induced in it. (ii) When the coil rotates in a magnetic field, its effective area, i.e. A cos θ, (i.e. area normal to the magnetic field) keeps on changing.
Draw a neat and labelled diagram of suspended coil type moving coil galvanometer. Two very small identical circular loops, (1) and (2), carrying equal currents I are placed vertically (with respect to the plane of the paper) with their geometrical axes perpendicular to each other as shown in the figure.
