Question

The alternating current in a circuit is described by the graph shown in Figure. Show rms current in this graph.

Answer 1

Step 1: Draw a rough diagram

Step 2: Find rms value of current.

From Figure.

$I_{rms}=\sqrt{\frac{1^2+(-2{)}^2}{2}}$


$I_{rms}=\sqrt{2.5}=1.6A$, as shown in graph

Final Answer: $1.6A$
