Why does a wire get warm if a current runs through it?
A. An electric field in the wire accelerates the charge carriers, increasing their kinetic energy and the thermal energy is nothing but the average kinetic energy of the charge carriers.
B.An electric potential difference results in an electric field that accelerates the charge carriers, which frequently collide randomly with stationary atoms, transferring part of their energy to the atoms.
C.The charge carriers create an electric field, which accelerates nearby atoms, thereby increasing the kinetic energy of the atoms and hence adding thermal energy to the wire.
D.Current is the change in charge (Delta q) over the change in temperature (Delta T), so if current I is constan, then an increase in charge moved implies a proportional increase in temperature.
Option B.An electric potential difference results in an electric field that accelerates the charge carriers, which frequently collide randomly with stationary atoms, transferring part of their energy to the atoms.
Option B is enough explanation not your question ,doesn't need further explanation.
If u stil have any doubt Feel free to ask.

A constant electric field accelerates a proton from rest through a distance of 1.65 m to a speed of 1.77 ✕ 105 m/s. (The mass and charge of a proton are mp = 1.67 ✕ 10−27 kg and qp = e = 1.60 ✕ 10−19 C.) HINT (a) Find the change in the proton's kinetic energy (in J). J (b) Find the change in the system's electric potential energy (in J). J (c) Calculate the magnitude of the electric field...
