    Q&A

    A series RLC circuit consists of a 50Ω resistor?

    A series RLC circuit consists of a 50Ω resistor, a 3.3 mH inductor, and a 480 nF capacitor. It is connected to a 5.0 kHz oscillator with a peak voltage of 5.0 V.

    What is the instantaneous current i when E = E 0?

    What is the instantaneous current i when E =0V and is decreasing?

    1 Answer

    Calculate the impedance:

    R = 50 Ω (real component)

    Reactance, X = 2πfL – 1/(2πfC)

    = 2π(5.0 kHz)(3.3 mH) – 1/[(2π)(5.0 kHz)(480 nF) = 37.4 Ω

    (imaginary component, mainly inductive)

    Z = 50 + j37.4

    |Z| = sqrt(50² + 37.4²) = 62.4 Ω

    θ = arctan(37.4/50) = 36.8° lag

    Peak Current = 5.0 V / 62.4 Ω = 80 mA

    According to “ELI the ICE man”, the current lags the voltage in an inductive circuit.

    When E = E0, this corresponds to an angle of 0°. Therefore, the current is at -36.8°

    i = 80 mA cos (-36.8°) = + 64 mA (forward)

    When E = 0V decreasing, this corresponds to 90°. Current is at 90° – 36.8° = 53.2°

    i = 80 mA cos (53.2°) = + 48 mA (forward)

    R-L-C Series Circuits

    An R-L-C series circuit is an electronic circuit composed of a resistor, an inductor, and a capacitor. The impedance of the inductor and the capacitor differs from that of the resistor in such a way that the frequency of the input voltage is taken in consideration.

    Impedance formula for Inductor

    Z L = 2 Π f L j ZL=2ΠfLj

    Impedance formula for Capacitor

    Z C = − 1 2 Π f C j ZC=−12ΠfCj Where:

    f = frequency of the source

    C = capacitance L = Inductance

    j = the symbol for the imaginary number (j was used instead of i in order to avoid confusion with current).

    Help with AC Circuits in RLC Series

    Hey guys, I need help with this physics question.

    "A series RLC circuit consists of a 50 ohm resistor, a 3.3 mH inductor, and a 480 nF capacitor. It is connected to a 3.0 kHz oscillator with a peak voltage of 5.0 V. What is the instantaneous emf when:

    a) i = I b) i = 0 A and is decreasing c) i = -I "

    Please also explain all the steps and a bit of the theory behind it. I'm still feel very confused whenever I'm dealing with AC Circuits.

    How does a nuclear bomb explode in a vacuum? On Earth, a nuclear explosion is destructive because there is an atmosphere, and the explosion heats up the air very much and creates a huge blast wave. But will there be such a destructive nuclear bomb in space where the vacuum is?

    Is there a difference between left and right?

    In school i heard about the right-hand-rule for magnetic fields and that made me think if there was actually a physical difference between the relative directions right and left. If the universe was mirrored, would everything be the same or would some things behave differently?

    Can I indulge myself in Pop Science ocassionaly?

    I'm a first year undergrad in physics. While I do know that pop science is often wrong and doesn't give an actual understanding of the topic beforehand, could I still for recreation read pop sci books? Don't get me wrong but I love all the mind bending concepts like blackholes, string theory, time travel, multiverse. I'm aware that concepts like these are relatively advanced and will take a lot of time before I reach them through the standard roadmap of physics. Therefore I justify reading their pop sci version by treating them as more or less fiction.

    Does the start of the Big Bang have an exact date and time?

    I'm not asking whether we can calculate it or not, the answer is certainly no.

    My question is: if we extended the Gregorian calendar back in time, could we in theory assign a date and time to the beginning of the expansion of the universe?

    For example, one possible date could be July 28th 13,782,742,945 BC 11:04:33 pm.

    I understand most physics pretty well but have a rough time with electricity. Can I get an understanding check?

    edit: I still have questions but I'm getting there (I think). Thank you everyone who has/will spare their time for my relentless curiosity. The answers have been insightful.

    So I was once told by a friend that's knowledgable in these things that it's reasonable to make an analogy between a stream running down a hill and electricity.

    Can someone verify that the following makes sense?

    In that situation, voltage is the amount of potential energy that's converted to kinetic energy (dependent upon the mass of the stream at any given moment times the difference in height). And current would be... well, the speed of the stream at a given point. Resistance would be the wheelhouse that's utilizing the kinetic energy of the stream to perform some work (or at least release the energy in the form of heat). The resistance created by a long piece of wire would be like all the rocks and moss that slow the water down.
