1. Important Physics Formula For NEET - Series LCR Circuit

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.
$\mathrm{v}_{\mathrm{R}}=\mathrm{iR} \rightarrow$ Voltage is in phase with i
$\mathrm{v}_{\mathrm{L}=\mathrm{i} \omega \mathrm{L}} \rightarrow$ voltage is leading i by $90^{\circ}$
$\mathrm{v}_{\mathrm{c}}=\mathrm{i} / \omega \mathrm{c} \rightarrow$ voltage is lagging behind i by $90^{\circ}$

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

So, from the above phasor diagram, V will represent the resultant of vectors V_R and (V_L -V_C). 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
\end{aligned}
$

where,

$
Z=\sqrt{R^2+\left(\omega L-\frac{1}{\omega C}\right)^2}
$

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

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

• General equation of SHM

1. For Displacement:-

$x=A \operatorname{Sin}(w t+\phi) ;$ where is initial phase and $(\omega t+\phi)$ is called as phase.

Various displacement equations:-

(1) $x=$ ASinwt $\Rightarrow$ when particle starts from mean position towards right.
(2) $x=-$ ASinwt $\Rightarrow$ when particle starts from mean position towards left.
(3) $x=A \operatorname{Cos} \omega t \Rightarrow$ when particle starts from extr eme position towards
(4) $x=-$ ACoswt $\Rightarrow$ when particle starts from left extreme position towards Right.

2. For Velocity (v):-

$\begin{aligned} x & =A \operatorname{Sin}(\omega t+\phi) \\ \Rightarrow v & =\frac{d x}{d t}=A \omega \operatorname{Cos}(\omega t+\phi)=A \omega \operatorname{Sin}\left(\omega t+\phi+\frac{\pi}{2}\right)\end{aligned}$

3. For Acceleration:-

$
\begin{aligned}
x & =A \operatorname{Sin}(\omega t+\phi) \\
\Rightarrow v & =\frac{d x}{d t}=A \omega \operatorname{Cos}(\omega t+\phi)=A \omega \operatorname{Sin}\left(\omega t+\phi+\frac{\pi}{2}\right) \\
\Rightarrow a & =\frac{d v}{d t}=-A \omega^2 \operatorname{Sin}(\omega t+\phi)=A \omega^2 \operatorname{Sin}(\omega t+\phi+\pi)=-\omega^2 x
\end{aligned}
$

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:-

$\begin{aligned} & \frac{d v}{d t}=-\omega^2 x \\ & \Rightarrow \frac{d}{d t}\left(\frac{d x}{d t}\right)=-\omega^2 x \\ & \Rightarrow \frac{d^2 x}{d t^2}+\omega^2 x=0\end{aligned}$

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

Important formulas from Solubility and solubility products for NEET 2025

General Representation$\begin{aligned} & \mathrm{A}_{\mathrm{x}} \mathrm{B}_{\mathrm{y}} \rightleftharpoons \mathrm{xA} \mathrm{A}^{+y}+\mathrm{yB}^{-\mathrm{x}} \\ & \mathrm{Ksp}=\left[\mathrm{A}^{+y}\right]^{\mathrm{x}} \times\left[\mathrm{B}^{-\mathrm{x}}\right]^y\end{aligned}$

Relation between Solubility(s) and Solubility Product (Ksp)
$A_x B_y \rightleftharpoons x A^{+y}+y B^{-x}$
