    It is a device based on wheat stone bridge it consist of 1 m long straight and uniform wire AC The wire is made up of manganin constantan because they have low temperature coefficient and large resistivity. Wire are soldered to two thick 1- shaped copper strips with binding terminal on a wooden board between these 1-shape strips there is a third copper strip. Thus between the strips there are two fixed gap Ab and CD in meter scale is also tittled on the wooden board parallel to the length of wire Across 1 gap a resistance box R and another gap the unknown resistance S are connected a jockey B can be slided on the bridge wire one terminal of the sensitive galvanometer is connected to jockey B and the other to the terminal D the positive terminal of the battery E is connected to terminal A and negative pole of the battery to come battery to terminal c through a one way key k. This circuit is now same as that wheat stone bridge.

    Resonant frequency is the natural frequency where a medium vibrates at the highest amplitude. Resonant frequency is usually denoted as f0. Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.

    • Electric potential is the work done per unit charge to Potential difference is the bring the charge from infinity to a point in an electric difference between the field. potentials between two points in the electric field.
    • Electric potential is defined at a point.
    • Potential difference is defined between two points in electric field.
    • The unit of electric potential is volts.
    • The unit of potential difference is volts.
    • Electric potential is a scalar quantity.
    • Potential difference is also a scalar quantity.
    • Electric Potential is taken as zero at infinity.
    • There is no as such concept for potential difference.

    Mirage is caused due to total Internal Reflection of light by the various layers of air. It is an optical illusion which is responsible for the appearance of the water layer at short distances in a desert or on the road. Mirage is an example of total internal reflection which occurs due to atmospheric refraction.

    Biot Savart law states that the magnetic field due to a tiny current element at any point is proportional to the length of the current element, the current, the sine of the angle between the current direction and the line joining the current element and the point, and inversely proportional to the square of the distance of that point. The direction of the magnetic field is in the direction of dl cross r. You can also use the right hand clasp rule to figure out the direction

    We use shunt resister to free up galvanometer from flowing more current as galvanometer measure only small unit of current so in case of this we use a resister i. e parrallel to the galvanometer resister in the circuit to detect the current in galvanometer

    When a moving coil galvanometer is connected in parallels with a shunt resistor, the galvanometer can be used to find the amount of current flowing through the circuit and thereby, can behave as an ammeter.
