ok thanks for the help

sorry i don't get it...im trying to make the general solution...from the question i(0) = 12

Im doing separation of variables now and I am stuck...ive come up to this stage -5 ln 2-3i = t^2/2 + C my problem is do i need to divide the C and t^2/2 by -5? or don't divide the C? please help me.. thnks

What answer did you get? my answer is 7.5x10^-4[ 1 - e^-18.75t(cos 456.05t + 41.11x10^-3 sin 456.05t)

hi, does anyone know how to produce ramp voltage using simulation? what components or circuits i need to use? thanks, helps really appreciated.

im trying to understand the mutual inductance in induction motor operation...How the mutual inductance occur in induction motor? what it does with the rotating magnetic field?

sorry i don't get the idea of how it end up that way...mind to explain? thnks

i don't get the fraction decomposition... when i multiplied inside the bracket it gives me...(15s^2 + 0.4s^3 + 83.333x10^3 s) is this correct and what to do next?

i stuck on the 1/s^2 [r + sL + 1/sC] ...do we need multiply all inside the bracket by s^2?

can anyone give me the working examples of current expressions of series RLC circuit using ramp voltage by Laplace transforms. thanks R=15, L= 0.4H, C=12uF ...voltage 5v

it is the voltage at a and d...

the voltage I am after is at 'a'...the voltage coming out from the capacitor which is the output voltage waveform

the voltage I am concerned with is the output voltage (the last voltage coming out through all the components)...with all the voltages connected (in series) in one circuit.

v = 110sinωt + 22sin(3ωt + 50⁰) + 5.5sin(5ωt - 35⁰) R = 25 , L = 100mH , C = 11.3uF ...in RLC series circuit Freq = 50Hz that are the details of the circuit...

Hi...i have question on RLC circuit. Why my max.voltage of complex sinewave in Excel is different from the simulated complex waveform? which one is right? max.voltage of complex waveform in excel = 106.8V max.voltage of complex waveform in simulation = 126.8V Should it be the same?
