    A drop in voltage occurs

    Explanation:

    When electric current flows through a conduct, there are three basic electrical effects that occur to the conductor;

    1. A magnetic field is set up around the conductor,

    A magnetic field is formed around a conductor when current flows through it which makes it acts like a magnet. Application is used in electric bells.

    2. Heat is generated, and

    The heating effect of current is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. Application of heat effect include electric iron, microwave oven, electric bulb, hair straightener etc.

    H = I²Rt

    3. A drop in voltage occurs

    Voltage drop is as a result of current passing through the impedance offers by the conductor or circuit elements. When current passes through a conductor, the resistance offers opposition to the flow of the electric current according to Ohm's law.
