Nadya [2.5K]4 years ago
3 0

Answer: Option (a) is the correct answer.

Explanation:

Metals are the substance which have excess of electrons. Therefore, they are good conductors of heat and electricity as they have mobile electrons.

Out of the given options, iron is a transition metal which are good conductors of heat and electricity.

Sulfur and carbon are non-metals, therefore, they are bad conductors of heat and electricity.

Tin is a poor metal so it will not conduct electricity effectively as compared to iron.

Thus, we can conclude that out of the given options, iron is likely to be the best conductor.

A 190 mH inductor is connected to an emf given by
Bas_tet [7]

(a) The reactance of the inductor is 25.46 ohms.

(b) The expression for the current through the inductor is I(t) = (6.32 A) sin(134t)

<h3>Ractance of the inductor</h3>

The reactance of the inductor is calculated as follows;

XL = ωL

where;

  • ω is angular frequency
  • L is 190 mH

v(t) = (161 V) sin(134t)

v(t) =  V sin(ωt)

The reactance of the inductor is calculated as follows;

XL = (134) x (190 x 10⁻³)

XL = 25.46 ohms

<h3>Peak current in the circuit</h3>

I₀ = V₀/XL

I₀ = (161) / (25.46)

I₀ = 6.32 A

<h3>Expression for the current through the inductor</h3>

I(t) = (6.32 A) sin(134t)
