Question

A 120 volt AC source is connected across a pure inductor of inductance 0.70 henry. If the frequency of the source is 60 Hz, the current passing through the inductor is (A) 4.55 A (B) 0.355 A (C) 0.455 A (D) 3.55 A

Tardigrade Admin · Accepted Answer

Z=XL=2 π × 60 × 0.7 ∴ i=(120/Z) =(120/2 π × 60 × 0.7)=0.455 A.

Q. A $120$ volt AC source is connected across a pure inductor of inductance $0.70$ henry. If the frequency of the source is $60 Hz$ , the current passing through the inductor is

4.55 A

0.355 A

0.455 A

3.55 A

$Z = X_{L} = 2 π \times 60 \times 0.7$
$∴ i = \frac{120}{Z}$
$= \frac{120}{2 π \times 60 \times 0.7} = 0.455 A$ .
