Basic Electrical Mcqs


Q.  Internal resistance of ideal current source is ?

a. zero
b. infinite
c. finite
d. 100 ohms


ANSWER: See Answer
 
Ideal current source delivers energy at specified current, which is independent on voltage across the load. The internal resistance must become very high to deliver maximum current.
