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,

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

we need to know the time interval during which the force acts. impulse of force = momentum change
