The alternating current in a circuit is ...

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

Text Solution

Verified by Experts

The correct Answer is:
A
`I_("rms")=` rms current
`=sqrt(1^(2) + 2^(2))/2=sqrt(5//2)~~ 1.6A`

The rms value of the current `(I_(rms))` =1.6 A is indicated in the graph.
