What method does an electric boiler use to generate heat?

• A. Chemical reaction
• B. Electrical resistance or an electric arc
• C. Burning fuel
• D. Heat transfer from water

Answer: (B)

An electric boiler generates heat by utilizing electrical resistance or an electric arc. In this process, electricity flows through heating elements, which are typically made of materials that resist the flow of electrical current. As the current passes through these elements, they convert electrical energy into heat. This heat is then transferred to the water or fluid within the boiler, raising its temperature for various applications, such as space heating or producing steam. This method is highly efficient since it directly converts electricity into heat without the need for combustion or chemical reactions, making it a clean energy source. Unlike other methods, electric boilers do not require fuel storage or venting for exhaust gases, simplifying installation and reducing maintenance concerns.
