The underline principle for the working of electric fuse is based on the heating effect of electric current. A fuse wire has a low melting point and high resistance. When an excessive current flows through it, the wire melts, and the circuit is broken.
a. In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. If one bulb burns out in a series circuit, the entire circuit is broken.
b. Magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles. Magnetic Field is a vector quantity because it has both magnitude and direction.
c. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R. Current in gases and liquids generally consists of a flow of positive ions in one direction together with a flow of negative ions in the opposite direction.
d. When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called the heating effect of current.
