Question

Statement 1 -electric current ( flow of electrons )create heat in the resistor
Statement 2-heat in the resistor is created according to the rule of energy conservation
Explain statement 1 with the help of statement 2

Answer 1

hey mate

here is your answer

1- when electrons move in a circuit then work done by electrons against the resistance gets converted into heat.

2-i- is called critical angle.

the value of r for I is 90°.

the process of returning in dense medium is called total internal reflection.

total internal reflection is the phenomenon due to which a ray of light passing from denser to rarer medium when the angle of incidence is greater than critical angle .
