Question

An AC voltage source has an output of Δ V=(200 V) sin 2π ft. This source is connected to a 100 Ω resistor. RMS current in the resistance is (A) 1.41 A (B) 2.41 A (C) 3.41 A (D) 0.71 A

RMS current in the resistance I0 =(V0/R)=(200/100)=2 A I rms =(I0/√2)=1.414 A

Q. An $A C$ voltage source has an output of $Δ V = (200 V) sin 2 π f t$ . This source is connected to a $100 Ω$ resistor. $RMS$ current in the resistance is

1.41 A

2.41 A

3.41 A

0.71 A

RMS current in the resistance
$I_{0} = \frac{V _{0}}{R} = \frac{200}{100} = 2 A$
$I_{r m s} = \frac{I _{0}}{2} = 1.414 A$
