both option B and C are correct

Question:

In a practical voltage source, the terminal voltage

Options:
A)

cannot be less than source voltage

B)

cannot be higher than source voltage

C)

is always more than source voltage

D)

is always equal to source voltage

Solution:

Ans: (b)

A practical voltage source has some source resistance.

Because of voltage drop across source resistance, terminal voltage cannot be higher than source voltage.

If current is zero, terminal voltage and source voltage are equal.
