GenaCL600 [577]

Answer:

\rho=1.8\times 10^{-8}\Omega.m

Explanation:

Given:

width of the wire, w=1.8\ mm=1.8\times 10^{-3}\ m

thickness of the flat wire, d=0.12\ mm=1.2\times 10^{-4}

length of the wire, l=12\ m

voltage across the wire, V=12\ V

current through the wire, I=12\ A

Now the net resistance of the wire:

using ohm's law

R=\frac{V}{I}

R=\frac{12}{12}

R=1\ \Omega

We have the relation between the resistivity and the resistance as:

R=\rho.\frac{l}{a}

where:

a = cross sectional area of the wire

\rho = resistivity of the wire material

1=\rho\times \frac{12}{1.8\times 10^{-3}\times 1.2\times 10^{-4}}

\rho=1.8\times 10^{-8}\Omega.m

2. A 1.54 kΩ resistor is connected to an AC voltage source with an rms voltage of 240 V.
svp [43]

(a) The maximum potential difference across the resistor is 339.41 V.

(b) The maximum current through the resistor is 0.23 A.

(c) The rms current through the resistor is 0.16 A.

(d)  The average power dissipated by the resistor is 38.4 W.

<h3>Maximum potential difference</h3>

Vrms = 0.7071V₀

where;

  • V₀ is peak voltage

V₀ = Vrms/0.7071

V₀ = 240/0.7071

V₀ = 339.41 V

<h3> rms current through the resistor </h3>

I(rms) = V(rms)/R

I(rms) = (240)/(1,540)

I(rms) = 0.16 A

<h3>maximum current through the resistor </h3>

I₀ = I(rms)/0.7071

I₀ = (0.16)/0.7071

I₀ = 0.23 A

<h3> Average power dissipated by the resistor</h3>

P = I(rms) x V(rms)

P = 0.16 x 240

P = 38.4 W
