the wire will burn red hot or desinigrate instantly
electric current
A circuit breaker is a device used to open a circuit if too much current flows through it.
No current flows when the the voltage is zero.
When too much current flows through a conductor, it is called an overload. This can lead to overheating and may damage the conductor or the connected equipment if not addressed.
If no current flows through a load, then no energy is received by the load. Energy is transferred through the flow of current, so without any current, there is no energy transfer to the load.
It varies with exactly where the current flows through the body, but a tenth of an amp will almost always kill, as little as a quarter of that has on occasion. The cause of death is cardiac arrhythmias and not the electricity itself.
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped .
Overcurrent, sometimes called shortcircuit.
same current flow in each bulb
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
3 Ampere
This would not be a hypothesis, but an explanation. A fuse is a piece of wire with a low melting point which melts if too much current flows in the circuit. It is designed to break before the rest of the circuit is damaged.
