figure 1 shows dc model of CB transistor, why is it that collector diode is taken as current source in equivalent circuit, why not emitter is also taken as current source ?

in the attached diagram its seen that while drawing AC equivalent of the common emitter circuit, Re is not taken in, the AC equivalent diagram no.2. why?

Forget about reality, Iam just giving a concept so that someone can tell me how is differential equation useful in practical cases.

So light intensity will be zero at point B

It decreases by 1 unit for every metre from A to B

Take light intensity as 10 at point A

[ NOTE ] Thread moved to homework forums by mentor suppose in a dark room a candle is burning, so darkness increases as we move away from the candle. from the below diagram can anyone derive a differential example to show the rate of change of darkness from candle to point B. supposing...

thanks for your reply sir, ok so it means that d=f(t) and also t=f(d), now as you said if distance is never same for two different times then t=f(d), but wat if the car comes to halt at time t=6, wether still time can be said as function of distance t=f(d)?

The distance covered by a car at time t=0 is 0 / at time t= 1 is 10 km/ at time t= 5 is 50 km, With this example can you explain, what is function of what? f(d) or f(t),
