    A galvanometer is a device (instrument) used for detecting feeble electric voltage, currents in a circuit. It has a coil pivoted (or suspended) between concave pole faces of a strong laminated horse shoe magnet. When an electric current passes through the coil it deflects. Its deflection is noted by attaching a pointer to the coil (or by using a lamp and scale arrangement). The deflection is proportional to the current passed.
    The galvanometer coil has a moderate resistance (about 100 ohms) and the galvanometer itself has a small current carrying capacity (1 mA).

    Van de graaff generator is used to generate high voltages of the order of a few million volts. This results in generation of large electric fields for experimental purposes.
    Principle :

    • The inner sphere has a higher potential than outer if the charge q is positive.
    • If the two spheres are connected through a wire, the charge will flow from high to low potential.
    • Thus, providing smaller potentials at the inner sphere will keep building large amount of charge at the outer sphere, till the breakdown field of air (3 x 106 V/m) is reached.
    • This accumulates close to millions of volts.

    A Transformer is used to convert low voltage (or high current) to high voltage (or low current) and vice versa. It is based on the principal of electromagnetic induction.
    The working principle of transformer is very simple. Mutual induction between two or more windings is responsible for transformation action in an electrical transformer.

    Wheatstone bridge is used to measure the unknown resistance connected in a circuit. It consists of four resistors of which two resistors are known resistors, one variable resistor and one unknown resistor. It also consists of a galvanometer. It consists of two series-parallel arrangements of resistors.
