    Ammeter only tells the amount of current but galvanometer at the same time can be used to check the change in direction of current

    1Thank You

    Najirul Husaain 7 years, 3 months ago

    Ammeter is used to measure the current flowing through a circuit. Galvanometer is used to check the presence of current

    We consider that the voltmeter has infinite resistance and when we connected it in parallel, it gives 0 resistance as 1 /infinity is 0. In the case of ammeter, we consider the internal resistance of ammeter to be 0, hence it is connected in series.

    The electric dipole is a system consist of two equal and opposite charges are separated by very small distance 2a...........electric dipole moment is the product of either charge dipole and distance between both charges.........and its direction is -ve to +ve

    1Thank You

    Shivam Dhruw 7 years, 3 months ago

    The direction of dipole is always from -ve to +ve..... By the experiment when the dipole is in the the uniform electric field then its experience the couple force which is called torque..... By there the -ve charge will be attracti & displace towards the source charge & +ve charge will be repule & moving outwards from the source charge... But the dipole is moving moving outwords becz of +ve source charge.... Now... The dipole direction is considered from its pole is -ve to +ve direction
