No. That is not the purpose of a GFI.
Uhhh... the short answer is "everywhere".
Blaniers Test is used in electronics to establish and locate short circuits and/or open circuits in cabling systems. It is a simple continuity test.
Fuses and circuit breakers are used to protect the wiring and devices from overload and heating caused by short circuits, short circuits that, if unprotected, could cause major damage and/or fire due to excessive current.
Electronic devices use all sorts of complicated electronic circuits - amplifier circuits for example, and switching circuits. The details, however, are a bit complicated for a short answer.
MCB, Miniature Circuit Breaker is electric switch which is used to protect against short circuits
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
It depends where you live.In most countries, radial circuits are used for both power and lighting circuit.In the UK, ring-main circuits are used for power circuits, while radial circuits are used for lighting circuits.
Simple electronic circuits are used in simple electronic devices.
Overload protection Short circuit protection Earth leakage protection
Dozens of functions. Short term power storage. Smoothing. Decoupling, Coupling, Voltage doubling. Resonant circuits. Phase shifting. Timing circuits. Delay circuits. Lumped constant delay lines as used in radar modulators. And many more...I even used one once as a poor man's one bit RAM.
If this is in a house, just watch the meter used by the power company for power. It is easier if the meter is the older type with the spinning wheel. First see how fast the wheel is spinning or how much energy is being used normally, no circuits turned off. Second go to your circuit breaker panel. Turn off all circuits except for the main. Check your meter to see if it has stopped moving, or if energy is no longer consumed. If it hasn't, your short is between your meter and the main switch. If it has stopped, go back to the panel and turn on each of the circuits one at a time until you find the one that consumes the most energy or spins the wheel the fastest. From here you will know which circuit to troubleshoot and repair if necessary.
RC circuits can be used to filter a signal by blocking certain frequencies and passing others.
