I have two questions I'm having trouble understanding. I greatly appreciate any help you all can give me! I'm not great at physics so the more details the better.
THANKS!!!
QUESTIONS-2 :
(a) The amplitude of current will be given as :
using an ohm's law, we have
Imax = max / R = (100 V) / (10 )
Imax = 10 A
And the phase constant will be given as :
using a formula, we have
= tan-1 [XL - XC / R]
where, XL = inductive reactance = L = (4000 s-1) (0.4 H)
XL = 1600
XC = 1 / C = 1 / (4000 s-1) (2 x 10-6 F)
XC = 125
then, we get
= tan-1 [(1600 ) - (125 ) / (10 )]
= tan-1 (147.5)
= 89.6 degree
(b) The ratio of the potential-difference amplitude across the inductor to the potential-difference amplitude across the capacitor which is given as :
VL / VC = I XL / I XC
VL / VC = (XL / XC) = (1600 ) / (125 )
VL / VC = 12.8

Derive equations 1 and 2, thank you! When you have a RC series circuit in an AC source of angular frequency ω (ω = 2πf), you can calculate the capacitance (C) from the equation: max, where VmarR is the amplitude of the voltage across the resistor and Vmax.c is the amplitude of the voltage across the capacitor. [You have to derive this equation in your report.] Similarly, when you have a RL series circuit in an AC source of angular...
Can you please explain Q7.2? I have the answers here, but I'm having trouble understanding what is happening to the circuit when the switch is at b. How is it possible to draw a circuit this way when there is no return path? (please see my hand drawing). 7.2 At 0, the switch in the circuit shown moves instantaneously from position a to position b a) Calculate vo for t 0. b) What percentage of the initial energy stored in...
You have a 206 −Ω resistor, a 0.399 −H inductor, a 5.06 −μF capacitor, and a variable-frequency ac source with an amplitude of 3.00 V . You connect all four elements together to form a series circuit. 1) In units of rad/s, at what frequency will the current in the circuit be greatest? 2) What will be the current amplitude at this frequency? 3) What will be the current amplitude at an angular frequency of 391 rad/s ?

I'm having trouble writing this code, can some help me? Step 1: Capturing the input The first step is to write a functionGetInput()that inputs the expression from the keyboard and returns the tokens---the operands and operators---in a queue. You must write this function. To make the input easier to process, the operands and operators will be separated by one or more spaces, and the expression will be followed by #. For example, here’s a valid input to your program: 6...
