4.
Henry is equivalent to
Volts/Ampere
Weber/Volt
Weber/Ampere
Weber/Ampere2
Answer: Option

5.
In a minimum function
the degree of numerator and denominator are equal
the degree of numerator and denominator are unequal
the degree of numerator is one more than degree of denominator
the degree of numerator is one less than degree of denominator
Answer: Option
Explanation:

If degrees of numerator and denominator were unequal, a pole or zero can be removed. Such a function cannot be a minimum function. Therefore degrees of numerator and denominator must be equal.
