Given: A material with a bulk resistivity of p = 120 Om is to be used to manufacture a 75 kO resistor that must dissipate P = 80 W of power. The maximum allowable current density for this material is J = 120 A/m2. The shape of the resistor is a rectangle.
Required: Determine the resistor length in cm, cross-sectional area in cm2, the maximum allowable applied voltage and the maximum allowable current.
