1. Important Physics Formula For NEET - Series LCR Circuit 1714040187791

Let 'i' be the amount of current in the circuit at any time, and VL, VC, and VR the potential drops across L, C, and R, respectively.
\begin{array}{l}{\mathrm{v}_{\mathrm{R}}=\mathrm{i} \mathrm{R} \rightarrow \text { Voltage is in phase with i }} \\ \\ {\mathrm{v}_{\mathrm{L}=\mathrm{i} \omega \mathrm{L}} \rightarrow \text { voltage is leading i by } 90^{\circ}} \\ \\ {\mathrm{v}_{\mathrm{c}}=\mathrm{i} / \mathrm{\omega} \mathrm{c} \rightarrow \text { voltage is lagging behind i by } 90^{\circ}}\end{array}\varepsilon

By all these, we can draw phasor diagram as shown below -

1714040187642

So, from the above phasor diagram, V will represent the resultant of vectors VR and (VL -VC). So the equation becomes -

\begin{aligned} V &=\sqrt{V_{R}^{2}+\left(V_{L}-V_{C}\right)^{2}} \\ \\ &=i \sqrt{R^{2}+\left(X_{L}-X_{C}\right)^{2}} \\ \\ &=i \sqrt{R^{2}+\left(\omega L-\frac{1}{\omega C}\right)^{2}} \\ \\ &=i Z \\ \text { where, } & \\ Z &=\sqrt{R^{2}+\left(\omega L-\frac{1}{\omega C}\right)^{2}} \end{aligned}

Here, Z is called the impedance of this circuit.

Now come to the phase angle. The phase angle for this case is given as -

\tan \varphi=\frac{V_{L}-V_{C}}{V_{R}}=\frac{X_{L}-X_{C}}{R}=\frac{\omega L-\frac{1}{\omega C}}{R}

2. Important Formulas For NEET Physics - Equations Of Motions Of SHM

1714040187952

As\ we \ know, a=-\omega^2x

  • General equation of SHM

  1. For Displacement:-

x=ASin(wt+\phi);\ where\ is\ initial\ phase\ and\ (\omega t+\phi)\ is\ called\ as\ phase.

Various displacement equations:-

(1)\ x=ASin\omega t \Rightarrow \ when\ particle\ starts\ from\ mean\ position\ towards\ right.

(2)\ x=-ASin\omega t \Rightarrow \ when\ particle\ starts\ from\ mean\ position\ towards\ left.

(3)\ x=ACos\omega t \Rightarrow \ when\ particle\ starts\ from \ extreme\ position\ towards

(4)\ x=-ACos\omega t \Rightarrow \ when\ particle\ starts\ from\ left\ extreme\ position\ towards\ Right.

  1. For Velocity (v):-

x=A Sin(\omega t+\phi )\\ \Rightarrow v=\frac{dx}{dt}=A\omega\ Cos(\omega t+\phi )=A\omega\ Sin(\omega t+\phi +\frac{\pi}{2})

  1. For Acceleration:-

x=A Sin(\omega t+\phi )\\ \Rightarrow v=\frac{dx}{dt}=A\omega\ Cos(\omega t+\phi )=A\omega\ Sin(\omega t+\phi +\frac{\pi}{2})

\Rightarrow a=\frac{dv}{dt}=-A\omega^2\ Sin(\omega t+\phi )=A\omega^2\ Sin(\omega t+\phi +\pi)=-\omega^2x

So, here we can see that the phase difference between x and v is \frac{\pi}{2}

Similarly, the phase difference between v and a is \frac{\pi}{2}

Similarly, the phase difference between a and x is \pi

  • Differential equation of SHM:-

\frac{dv}{dt}=-\omega^2x

\Rightarrow \frac{d}{dt} \left( \frac{dx}{dt}\right )=-\omega^2x

\Rightarrow \frac{d^2x}{dt^2}+\omega^2x=0

If the motion of any particle satisfies this equation, then that particle will do SHM.

Hello there,

If you are planning to appear for NEET in 2025, and continue you education after 2 years of passing, it wouldn't be possible. Your application, score and rank of the 2025 exam will not be counted after a year or two. In this case, you have to re-appear for the NEET Exam in 2027.

I hope this information suits you well.

Good Luck.

Orthotist and Prosthetist

Orthotists and Prosthetists are professionals who provide aid to patients with disabilities. They fix them to artificial limbs (prosthetics) and help them to regain stability. There are times when people lose their limbs in an accident. In some other occasions, they are born without a limb or orthopaedic impairment. Orthotists and prosthetists play a crucial role in their lives with fixing them to assistive devices and provide mobility.

Audiologist

The audiologist career involves audiology professionals who are responsible to treat hearing loss and proactively preventing the relevant damage. Individuals who opt for a career as an audiologist use various testing strategies with the aim to determine if someone has a normal sensitivity to sounds or not. After the identification of hearing loss, a hearing doctor is required to determine which sections of the hearing are affected, to what extent they are affected, and where the wound causing the hearing loss is found. As soon as the hearing loss is identified, the patients are provided with recommendations for interventions and rehabilitation such as hearing aids, cochlear implants, and appropriate medical referrals. While audiology is a branch of science that studies and researches hearing, balance, and related disorders.
