Question

I need some help in solving RLC ciruits.. Please help :)

Answer 1

its easy with KVL and laplace transform

Answer 2

first learn the formulas for R L C then automatically u vil get the process

Answer 3

V = R*dq/dt + q/c + L*d(dq/dt)/dt (serial connected RLC circuit)
dq/dt -> k*e^(jwt), (j = (-1)^0.5)
then
V = {R +1/(cjw) + Ljw}*ke^(jwt)
then rearrange right side, one is real part, the other is complex part
V(real part) = [R^2 + {Lw - 1/(cw)}^2]*k*cos(jwt-theta)
V(complex part) = [R^2 + {Lw - 1/(cw)}^2]*k*sin(jwt-theta)
theta is phasor differece between I to V

Answer 4

In order ro solve LRC circuits, you should have some background with exponents whicn are covered in Calculus II.
