Question

A $100\Omega$ resister is connected to a 220 V, 50 Hz ac supply. The rms value of current in the circuit is

• A. 1.56 A
• B. 1.56 mA
• C. 2.2 A
• D. 2.2 mA

Answer 1

Answer: (C)

2.2 A

$V_{rms}=220V$

$I_{rms}=\frac{V_{rms}}{R}$

$=\frac{220}{100}=2.2A$

Option $\left(C\right)$ is correct.
