Question

A variety of voltage source values were applied to the device shown in (Figure 1) .

A variety of voltage source values were applied to the device shown in ( Figure 1) The power absorbed by the device for each value of voltage is recorded in the table below. Use the values in the table to construct a circuit model for the device consisting of a single resistor from appendix H in the textbook. v(V)--8 -4 4 8 12 16 p(mW)-640 160 160 640 1440 2560 Determine the resistance of the device. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

P=V2/R

R=V2/P=64/640m=0.1K ohm=100 Ohm

Same value is true for all values of voltage and power..

So resistance of the device is 100 Ohm
