In the Leclanche dry cell the outer container itself is made of zinc and acts as the anode, being oxidised to zinc ions as the cell works, which is why an old cell often leaks when the container is eaten through.

Its reaction is reversible, so passing a current through it in the opposite direction converts the products back into lead and lead dioxide and the cell can be used again; such a cell is called a secondary or storage cell, and the car battery is the common example.

In the chlor-alkali process a concentrated solution of sodium chloride is electrolysed; chloride ions are oxidised at the anode and come off as chlorine gas, hydrogen is set free at the cathode, and sodium hydroxide remains in the solution, which is why the industry yields three useful products at once.

The metal ions in the plating bath carry a positive charge, so they move towards the negative electrode and are reduced to metal there; the article must therefore be the cathode for the coating to build up on it.

One faraday is the charge carried by one mole of electrons, obtained by multiplying the charge on a single electron by the Avogadro number, and it comes to about 96,500 coulombs; passing one faraday through an electrolyte liberates one gram equivalent of the substance at an electrode.

The anode is the electrode joined to the positive terminal of the supply, so negatively charged ions, the anions, travel to it and give up electrons there; loss of electrons is oxidation.

When cells are joined in parallel all their positive terminals are connected together and all their negative terminals together, so each cell is across the same two points and the voltage of the combination is the voltage of one cell, that is 12 volts.

The working rule for charging a storage battery is that the charging current should be about one-tenth of the ampere-hour capacity of the battery, which is called the C by 10 rate.

The agreement lists delivery of parcels paid for in advance and parcels paid for on delivery, confirmation of delivery through a one-time password, and tracking of a consignment in real time, along with faster delivery through closer operational coordination and shared technology.

The Department of Posts runs more than that many post offices across the country, which together make up the largest postal network in the world, and it is this reach that Blue Dart Express Limited gains under the agreement.

The Department of Posts, which works under the Ministry of Communications, signed the agreement with that company in New Delhi on 9 October 2026, in the presence of senior officers from both organisations.

The Department of Telecommunications presented a curtain raiser for the second conclave at the valedictory session, and it is scheduled from 27 to 29 October 2026 at that venue, guided by the Office of the Principal Scientific Adviser and organised by CSIR along with twelve participating ministries and departments, on…

It is an industry-led collaborative platform that brings together telecom service providers, industry, startups, academia and research institutions to advance the country's 6G ambitions, and it works on indigenous research and innovation, the creation of intellectual property, engagement with international standards and partnerships for an affordable, secure, sustainable and globally…

The correct answer is Dr. Chandra Sekhar Pemmasani, Minister of State for Communications and Rural Development, who closed the symposium at Yashobhoomi in Dwarka, New Delhi.

A key outcome of the symposium was the exchange of five new memoranda of understanding, with GSMA, one6G, the GTI Alliance, the 6G Innovation Forum of Taiwan and VOICE, which open the way to international cooperation, joint research, trials and the sharing of knowledge.

The minister made special mention of this award-winning initiative of the Department of Telecommunications, whose Samriddhi Kendras show how a single digital base can carry government services, health care, schooling, farming and village enterprise to rural communities, demonstrating that connectivity and home-grown innovation can support inclusive growth.

The India Mobile Congress is put together jointly by the Department of Telecommunications, which comes under the Ministry of Communications, and the industry body COAI.

The scale of the tenth edition is set out in a cluster of figures: an exhibition area of 60,000 square metres, participation from over 100 countries, more than 2,000 technology use cases, over 400 startups and more than 900 thought leaders, besides industry partners, exhibitors, investors, incubators and accelerators.

The tenth edition of the India Mobile Congress is being held at Yashobhoomi in New Delhi under that theme, organised jointly by the Department of Telecommunications of the Ministry of Communications and the Cellular Operators Association of India.

NCEL is National Cooperative Exports Limited, NCOL is National Cooperative Organics Limited and BBSSL is Bharatiya Beej Sahakari Samiti Limited, the national seed cooperative.
