0.04 Ampere of current will flow through the silicon.
<h3>
What is Electrical Current ?</h3>
Electrical current is the rate at which charges flow in the conductor. It is measured in Ampere (A)
What current flows through a 2.54cm diameter rod of pure silicon that is 20.0cm long ,when 1.00x10000V is applied to it
The given diameter is 2.54 cm, the radius r = 2.54/2 = 1.27 cm
Convert cm to m
Area A = πr²
A = π × 0.0127²
A = 0.000507 m²
The resistivity ρ of silicon material is 640 Ωm
Resistance R = ρL / A
R = ( 640 × 0.2 ) / 0.000506
R = 128 / 0.000506
R = 252964.43 Ω
From Ohm's law
V = IR
10000 = 252964.43I
I = 10000 / 252964.43
I = 0.0395A
Therefore, 0.04 Ampere of current will flow through the silicon.
