The alternating current in a circuit is described by the graph shown in Fig 7.4. Show RMS current in this graph.

Answers (1)

Explanation:-

The RMS current is the effective value of an alternating current (AC) that produces the same amount of heat in a resistive load as a direct current (DC) of the same value. The RMS value is particularly useful for AC because it allows us to compare the heating effect of AC with DC.

I_{rms}=\sqrt{\frac{\left ( 1^{2}+2^{2} \right )}{2}}=\sqrt{\frac{5}{2}}\cong 1.6A
