The heating effect of the fuse wire is caused by the collisions between moving electrons and stationary atoms. The correct answer is option c) collisions by moving electrons and stationary atoms.
When an electric current flows through a conductor like a fuse wire, it is carried by the movement of electrons. Electrons are negatively charged particles that move through the conductor due to the electric field established by the voltage applied across the wire.
Within the fuse wire, there are fixed or stationary atoms arranged in a regular lattice structure. As the electrons move through the wire, they collide with these stationary atoms. These collisions cause the atoms to vibrate or oscillate more rapidly, increasing their kinetic energy.
According to the kinetic theory of matter, an increase in the kinetic energy of particles is directly related to an increase in temperature. So, as the atoms in the fuse wire absorb the kinetic energy transferred during the collisions with the electrons, they heat up. This increase in temperature can eventually lead to the melting or breaking of the fuse wire, causing it to interrupt the flow of current and protect the circuit from excessive heat and potential damage.
To summarize, the heating effect of the fuse wire is caused by the collisions between moving electrons and stationary atoms, as the energy transferred during these collisions increases the temperature of the wire.
