A 2.0 m length of wire is made by welding the end of a 120 cm long silver wire to the end of an 80 cm long copper wire. Each pie

Levart [38]

<u>Explanation</u>:

Resistivity of silver wire = $1.47 e-8 ohm meter$

Resistivity of copper wire = $1.72 \mathrm{e}-8 \text { ohm meter }$

Resistance = Resistivity *length/cross sectional area

$R=\rho_{L / A}$

So,

$\begin{aligned}&I=A\left(V / P_{A g} L_{A g}+P_{C u} L C_{U}\right)\\&1=8104 \mathrm{A}\end{aligned}$

For E calculation

For copper

E = resistivity * current density

E = Resistivity * current/area

$E=4.9298 \mathrm{V} / \mathrm{m}$

For silver

$E=4.213 \mathrm{V} / \mathrm{m}$

Potential difference $=E^{*} L$

For silver

Potential difference = $4.213^{*} 1.2=5.055 \mathrm{V}$

For copper

Potential difference = $3.9438 \mathrm{V}$
