What happens if you connect a negative and positive wire?
Reversing the polarity in a circuit can ruin the power source or even cause an explosion. Connecting the wrong wires, like using a positive wire when it should be a negative wire, can also fry the wires themselves.
What happens if you connect both wires to the same end?
What happens if you connect both wires of a simple circuit to the same end of the battery? Nothing. No current flows because there still is no conductive path to the other end of the battery.
What happens if connect car battery backwards?
When a car battery is connected backward, a fuse designed to protect vehicle electronics should blow. If your vehicle doesn’t have a fuse (almost all cars do) designed for this purpose, you will send electrical current backward through systems in your car, including ECU, transmission control unit, and more.
Can two live wires touch?
You will receive a shock if you touch two wires at different voltages at the same time. You will receive a shock if you touch a live wire and are grounded at the same time. When a circuit, electrical component, or equipment is energized, a potential shock hazard is present.
What happens if you connect the black wire to the white wire?
It will produce a big spark and hopefully blow a fuse or trip a breaker. If you wire them together and then turn the power on, the spark will occur at the breaker or fuse. Either way, don’t do it.
What happens when a wire is connected to a battery?
When a wire is connected to the two terminals of the battery, the current flows from the positive to the negative terminal of the battery.
Why does an electric socket have two positive and negative terminals?
In ac system, electric socket doesn’t have positive and negative terminals. If you connect the two lines of an electric socket,it will be shorted and therefore produces huge amount of electric current which is considered as a fault in the system.
What happens to the current when a battery is too small?
So the maximum available current from the battery will flow through the wire and back to the battery. Power is I^2*R, so even if R is very small, the current will still be significant and so will be the power – and all that power does is make heat.
What happens if you put a battery in a hot conductor?
This current is sufficient to melt thick metal conductors, even metal bars and rods, the shorting conductor will quickly turn red hot within seconds, the battery will also heat up internally and if not properly ventilated may lead to an explosion. So it poses a serious risk. P.S.
