You are given a semiconductor resistor made from silicon with an impurity concentration of resistivity 1.00×10−3ωm. the resistor has a height of h =0.5 mm, a length of l = 2 mm, and a width of w = 1.25 mm. the resistor can absorb (dissipate) up to p = 7.81w. what is the resistance of the resistor (r), the maximum voltage (v), and the maximum current (i)?

Resistance = , Current = 1.56 A, Voltage =4.99 V

The resistance,

where, is resistivity, A is the area and l is the length of the resistor.

It is given that:

Length, l=2 mm

Area,

Hence,

We know, Power,

We know, Voltage,

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
