36.
When cells having different emfs are connected in parallel, a circulating current flows.
Answer: Option
Explanation:
To avoid circulating current cells in parallel should be identical.
37.
In a specimen of cast iron, a field strength of 400 AT/m cause a flux density of 0.6 T. In a specimen of silicon steel, the same value of H would cause B to be
Answer: Option
Explanation:
Since μr for silicon steel is more than that of cast iron, flux density will be more than 0.6 T.
38.
