Question

The alternating current in a circular is described by the graph as shown in figure. The rms current obtained from the graph would be

• A. 1.4 A
• B. 2.2 A
• C. 1.6 A
• D. 2.6 A

Answer 1

The correct option is C 1.6 A

$i_{rms}=\sqrt{\frac{1\times \frac{T}{2}+\frac{T}{2}\times 4}{T}}$

$=\sqrt{\frac{5T}{25}}=\sqrt{2.5}=1.58A$

Hence,

option $\left(C\right)$ is correct answer.
