Basic Electrical Mcqs

Q.  Which of the followings is/are active element?

a. Voltage source
b. Current source
c. Both
d. None of these


ANSWER: See Answer
 
Active elements are capable of delivering energy independently for long time or ideally infinite time. Both voltage and current source are active element and they can change energy level of a circuit.
