Option C

100A

Quick Summary: Given: Maximum value of current is 100A.

📋 Given

Maximum value of current is 100A.

🔢 Formula Used

Imax=ImI_{max} = I_mImax​=Im​

📊 Diagram / Illustration

🔢 Step-by-Step Solution

Understand the terminology

In alternating current (AC) circuits, the maximum value reached by a sinusoidal current waveform during one cycle is called the peak value or maximum value, denoted by $I_m$ or $I_{peak}$ .

Im=ImaximumI_m = I_{maximum}Im​=Imaximum​

Identify given values

The problem explicitly states that the maximum value of the current is 100A.

Imaximum=100AI_{maximum} = 100AImaximum​=100A

Conclude the result

By comparing the definition $I_m = I_{maximum}$ with the given value, we find that $I_m = 100A$ .

Im=100AI_m = 100AIm​=100A

✅

C is correct because the term $I_m$ represents the maximum amplitude (peak value) of the sinusoidal current, which is given as 100A.

💡 EXAM TIP

Always distinguish between Peak Value ( $I_m$ ), RMS Value ( $I_{rms} = \frac{I_m}{\sqrt{2}}$ ), and Average Value ( $I_{avg} = \frac{2I_m}{\pi}$ ) in electrical engineering problems.
