Latest FAQs
If a fuse blows, it breaks the circuit and stops the flow of current, protecting the appliances and preventing overheating or fire hazards. The fuse must be replaced to restore the connection.
Alternating current (AC) is used for domestic supply because it is more efficient for transmitting electricity over long distances. AC can be easily transformed to different voltage levels, which reduces energy losses in transmission.
A fuse is a one-time safety device that melts and breaks the circuit if excess current flows. An MCB (Miniature Circuit Breaker) automatically trips during overload or short circuits but can be reset after the fault is corrected.
The earth wire provides a low-resistance path for leakage currents to flow into the ground. It protects users from electric shocks by safely directing excess current away from the appliance in case of a fault.
Appliances are connected in parallel in domestic circuits to ensure that each receives the same voltage and operates independently. This setup also allows individual control of devices, so if one appliance fails, the others continue to function.
Around a bar magnet, magnetic field lines emerge from the north pole, curve around the magnet, and enter the south pole. Inside the magnet, the lines continue from the south pole to the north pole, forming closed loops.
You can visualize magnetic field lines by sprinkling iron filings around a magnet or by using a small compass. The iron filings align themselves along the magnetic field lines, forming a pattern that reveals the field’s shape and direction.
Magnetic field lines are imaginary lines used to represent the strength and direction of a magnetic field. They help us visualize how the magnetic force behaves around a magnet or a current-carrying conductor.
An electric fuse protects appliances from damage by breaking the circuit if excessive current flows, preventing overheating and potential fires.
Fleming’s Left-Hand Rule is used to find the direction of force on a current-carrying conductor in a magnetic field. It’s applied in electric motors to understand the direction of motion.
Electromagnetic induction is used in devices like electric generators, transformers, and in technologies like magnetic levitation for high-speed trains (Maglev).
Electromagnetic induction is the process by which a changing magnetic field induces a current in a conductor. Michael Faraday discovered this phenomenon.
The magnetic field strength inside a solenoid increases as the number of turns increases, as each turn reinforces the magnetic field at the center of the solenoid.
