A metal plate is getting heated. It can be because of:
A. An alternating current is passing through the plate.
B. It is placed in a time varying magnitude field.
C. A direct current is passing through the plate.
D. It is placed in a space varying magnitude field, but does not vary with time.
E. It is placed in a time constant magnetic filed.
Choose the correct answer from the options given below:
- A A, B, C Only
- B C, D, E Only
- C A, D, E Only
- D B, C, D Only
Answer & Solution
Correct Answer
(A) A, B, C Only
Step-by-step Solution
Detailed explanation
A. An alternating current (AC) is passing through the plate: Correct. When current (AC or DC) flows through a metal with resistance, electrical energy is converted into heat \(\left(H=I^2 R t\right)\). This is known as Joule heating. B. It is placed in a time-varying magnetic…
