The use of alternating current (A.C.) voltage is preferred over direct current (D.C.) voltage for two main reasons:
Easy Voltage Transformation: A.C. voltage can easily be stepped up or stepped down using transformers, making it efficient for long-distance transmission.
Simpler Generation and Distribution: A.C. generators are simpler and cheaper to design and maintain compared to D.C. generators, and A.C. can be easily converted to various forms of energy for different applications.
Two characteristic properties of materials suitable for making the core of a transformer are: High Magnetic Permeability: The material should have high magnetic permeability to efficiently conduct magnetic flux and reduce energy losses. Low Hysteresis Loss: The material should exhibit low hysteresisRead more
Two characteristic properties of materials suitable for making the core of a transformer are:
High Magnetic Permeability: The material should have high magnetic permeability to efficiently conduct magnetic flux and reduce energy losses.
Low Hysteresis Loss: The material should exhibit low hysteresis loss, meaning minimal energy is wasted when the magnetic field alternates, ensuring efficient operation of the transformer.
Two factors responsible for energy losses in actual transformers are: Core Losses: Due to hysteresis and eddy currents in the core material, resulting in heat generation. Copper Losses: Caused by the resistance of the windings, which generates heat when current flows through them. For more visit herRead more

When the lamp connected to an alternating voltage supply lights with the same brightness as when connected to a 12 V DC battery, the RMS value of the AC voltage is 12 V. The peak value (V peak ) is √2 × 12 ≈ 16.97V. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/Read more
When the lamp connected to an alternating voltage supply lights with the same brightness as when connected to a 12 V DC battery, the RMS value of the AC voltage is 12 V. The peak value (V peak ) is √2 × 12 ≈ 16.97V.
In a transformer, the power (ideally) remains unchanged. The input power in the primary winding is equal to the output power in the secondary winding, assuming no energy losses (ideal transformer condition).
