total electric current aa branch consists of a dc current of a 2a and an ac ammeter connected in this branch will read
Answers
Answer:
Explanation:
Concept:
- The one-way flow of electricity is known as direct current. DC power is best demonstrated using an electrochemical cell.
- Direct current may go through a conductor, like a wire, as well as through semiconductors, insulators, and even through a vacuum, such in electron or ion beams.
- It can also travel through semiconductors and insulators.
- Electrical current known as alternating current is characterized by periodic changes in the direction of electron flow.
- Alternating current is the type of current that travels through power lines and regular home electrical outlets.
- The value of 2A is displayed when the DC current is measured with an AC ammeter.
- So, the answer is 2A.

Answer:
The AC ammeter connected in the branch will read 2A.
Explanation:
The DC current flowing through the branch is 2A. DC current is a direct current or unidirectional current which flows only in one direction while an AC current is an alternating current that flows in alternate directions.
In this case, the DC current is flowing through a branch, and an ac ammeter is connected to that branch to take the reading. As current is unidirectional, so the ammeter will give the exact reading of the current that is flowing through the branch. That is it will show the reading as 2 A.
If the case is the opposite like AC current is flowing and DC ammeter is connected then it will show the average reading of AC current i.e., zero.
