There are two types of electricity - static and current. The current electricity is divided into Alternating Current (AC) and Direct Current (DC). Based on the production methods, electricity is divided into - heat, chemical, pressure, light and magnetism.

Yes, the Bihar Public Service Commission has released the BPSC 71st CCE Answer Key PDFs on its official website. The candidates can download their BPSC Prelims answer key and check their answer. The candidates will be allowed to send objections against the incorrect answers given in the  tentative answer key,

The objection sending window will open on September 21 and close on September 27.

There are four types of power supply - switch-mode power supplies, linear power supplies, linear power supplies, and programmable power supplies

According to this law, at any point, magnetic field due to a tiny current element is directly proportional to the current element length.

Tesla (T) is the SI unit of magnetic field. Tesla is named after Nikola Tesla.

If $P_1=P$ then $P_2=P+5\%$ of $P=1.05P.$

From Boyle’s law, $PV=constant$ therefore,

$\frac{V_2}{V_1}=\frac{P_1}{P_2}=\frac{P}{1.05P}=\frac{100}{105}$

Fractional change in volume is

$\frac{\Delta V}{V}=\frac{V_2-V_1}{V_1}=\frac{100-105}{105}=-\frac{5}{105}$

Therefore, percentage change in volume is

$\frac{\Delta V}{V}\times 100\%=-\frac{5}{105}\times 100\%=-4.76\%$

That is, volume decreases by $4.76\mathrm{\%}.$

To apply for CIEAT, candidates should have born on or after July 1, 2003.

To apply for CIEAT, Candidates must have passed class 12 with a minimum aggregate of 50% of marks in Mathematics/ Biology, Physics and Chemistry.

The different types of magnetism are - Diamagnetism, Paramagnetism, and Ferromagnetism.

The selection of candidates in CIEAT is solely based on the basis of CIEAT exam and JEE Main scores. 

CIEAT 2026 application form will be released in a few days. As of now there are no dates as to when the application form will be released.

 In SPSAT 2025, one mark will be awarded for every correct answer. There will be no negative marking.

SPSAT 2026 will be held as a computer-based test. The details about the examination will be released through the exam pattern.

SPSAT 2026 will be 60 minutes in duration. During the exam, the candidates will have to answer 40 multiple-choice questions.

The authorities may or may not release the SPSAT sample papers online. If released, the candidates will be able to access the sample papers in this page.

$As{V}^2=V_R^2+C_C^2$

$?V_R=\sqrt[]{V^2-V_C^2}=\sqrt[]{{10}^2-8^2}=6V$

$\tan ?\theta =\frac{X_C}{X_R}=\frac{V_C}{V_R}=\frac{8}{6}=\frac{4}{3}$  

Now,

The CIEAT 2026 exam date is not released as of now. As per the past year dates, the CIEAT exam will be conducted in April 2026 at Chennai centres as well as in other cities/centres.

The authorities are yet to announce the SPSAT 2026 exam date. The examination will be held as a computer-based test. The exam dates will be updated on the official website soon.
