Question

A $100\Omega$ resistor 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 A
• C. 2.2 A
• D. 2.2 mA

Answer 1

Answer: (C)

2.2 A

Answer 2

: Here, $R = 100\Omega,V_{rms} = 220V,\upsilon = 50Hz$ $\therefore I_{rms} = \frac{V_{rms}}{R} = \frac{220}{100} = 2.2A$
