Question

We are given an input current Iin=100μA and a linear resistive load represented by the resistor RL . Our resistive load is not regulated for the high current provided by our current source, so we add a resistor RS in parallel to divide the current such that IL≈40μA. An additional requirement is that the Thevenin resistance as seen from the load terminals is between 60kΩ and 80kΩ. Assume first that the resistors have their nominal resistance. Come up with resistors RS and RL such that the divider ratio IL/Iin is within 10% of the requirement.

Of course, the resistances you chose are just nominal. Given that they are only guaranteed to have resistances within 10% of the nominal value, what is the largest and smallest value that IL may have?

Answer 1

Enter your values below. (NOTE: Both resistor values are needed for a correct answer.)

RS (in Ohms):

RL (in Ohms):

ILmax (in Amps):

ILmin (in Amps):

Answer 2

RS (in Ohms): 100000

RL (in Ohms): 150000

ILmax (in Amps): 4.4e-5

ILmin (in Amps): 3.6e-5

Type all in at once, it does not accept one by one or errors!

Por favor ayudame con la respuesta en el segundo punto donde estan las resistencias optimas de 6.6 ohms. me falta la potencia, cual seria en ese caso. Hablo de la H2P2

Answer 5

Hi Spanish friend, can you write in English? I had to translate it online and could not understand it.

The answer is:

Consider a deuteron in a cyclotron with field strength 0.5T. The deuteron is accelerated twice per rotation by a potential of V=25 kV. (a) If the radius of the cyclotron is 2 meter, what is the maximum energy of the deuteron? Express your answer in Joules (the deuteron mass is 3.34×10−27kg) b)Starting from a negligibly small velocity, how many full rotations does the deuteron need before it reaches this maximum energy? c) What is the time it takes for the deuteron to make one complete rotation when its energy is about 500 keV and when it is about 5 MeV? Ignore possible relativistic effect

Answer 7

A current I travels counterclockwise through a closed copper wire loop which has the shape of a rectangle with sides a and b.
What is the magnitude of the magnetic field at the center, C , of the rectangle? Express your answer in terms of a, b, I and mu_0. (Enter mu_0)

Answer 8

ILmax and ILmin are wrong!
