Can u give me some definitions for ideal and real sources and how the ohm's law works with those! And how resistance affects the current in those sources. thanks and sorry really new with circuits and all!

Yeh V = R*I, Since for the first V = Constant, Then I = V/R, I = 1/r, but what is the difference between ideal, real, and voltage constant sources!, thanks

Hey guys I am new to Electrical Eng, i got a question to answer, it says that a variable resistor is connected to a " Constant Voltage Source", how does the current through the resistor changes as its resistance varies from zero to infinity? I also need with the same question, but with a...

i got it the dervaitve of the graph is 7.4t- 2 which equlas the velocity and then the acceleration is 7.4. thank u for all the help.

can u help me set it up please.

velocity is the slope of poistion/time

i got 7.4t-2 for derivative what should i do now.

another question i attached a graph and i just want to know how i can find the instataneous velocity at 3.3 second. Thanks for all the help. i am getting better.

the graph is a parabola when i graphed it.

i didnt learn about derivative yet please help. please give me an example.

An object moves along the x-axis according to the equation x(t) = (3.70t^2 - 2.00t + 3.00) m. how do i find its instantaneous speed at t = 1.70 s and at t = 3.20 s. acceleration between t = 1.70 s and t = 3.20 s. thank u. i just started calc 1. please help.
