d) Square of the current
c) Resistivity
me out out in microwave oven?
Answers
Answer:
Resistivity is one of the major factors that influence the amount of heat generated in heating elements.
Explanation:
Heat produced in a heating element or the conductor is the square of the current flowed in the conductor and the resistance of the heating element.
Hence resistance is important factor in heat generation.
'Current' depends on the amount of generated heat in heating elements.
Option (b)
Explanation:
The 'heating effect' of an 'electric depends on three factors'
- The 'resistance' R
- The 'Time' T
- The 'amount of current' I
The Resistance (R) of the conductor produces more heat
The 'longer the time' the 'larger amount of heat' is produced
The amount of current is higher the larger amount of heat is generated.
