Linear function Word Problem

It has been found through the series of experiments that voltage *V *at the semiconductor diode is related to the charge *Q *at the diode by the formula *V*(*Q*) = *V*0 (100.434*Q*/*Q*0 – 1),

where *Q*0 and *V*0 are some constant reference values measured in Coulombs and Volts, correspondingly.

** **

Find the ratio of *V*/*V*0 when the charge *Q *is 10% grater than *Q*0. Round off your answer to one decimal place.

Which charge (in Coulombs) on the diode is when the voltage is 0 Volts? Present your answer with one decimal palce.

Assuming that *V*0 = 0.001 V, find what is the voltage in the diod when its charge is 10 times greater than the reference charge *Q*0. Round off your answer to three decimal places.

Re: Linear function Word Problem

Can someone please show me how to work this problem out. I am confused by the Qo/Q and Vo/V. How do they relate to each other?

Re: Linear function Word Problem

I think your subscript is supposed to be a subscript: Is it

or

In either case, start by dividing both sides by so the left side is . If "Q is 10% greater than ", then so that and , approximately. Put that into the right side of the equation and do the calculations.
