What happens if positive and negative terminals touch?
If the terminal remains in firm contact with the post of the opposite polarity, nothing will happen. The charge will flow from the positive post of the battery to the negative post of the battery.
What would happen if we connected the positive and negative terminals of a battery with a conductor?
One terminal is marked (+), or positive, while the other is marked (-), or negative. If you connect a wire between the two terminals, the electrons will flow from the negative end to the positive end as fast as they can. This will quickly wear out the battery and can also be dangerous, particularly on larger batteries.
Should positive and negative be connected?
When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.” When you are replacing your car battery, It isn’t always easy to remember the order in which to disconnect and reconnect the terminals.
What happens when the positive terminal of a cell is connected to the positive terminal of another cell?
Answer: If one of the batteries is of higher voltage than the other, the battery with lower voltage will see an increase in voltage as the chemical reaction reverses in the battery with less voltage. The result is that the two batteries equilibrate to the same voltage.
What is the meaning of positive and negative terminal?
Usually applied to the terminals of a battery or some other form of power source. For ease of description, the Negative terminal has an abundance, or excess, of Electrons and the Positive one a lack, or depletion, of Electrons. Nature tends to find ways to neutralise these situations.
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 if you connect the + and – terminals together?
If you connect the + and – terminals to each other the external resistance goes to zero, and the only thing limiting the output power is the internal resistance. In the best case you will blow a fuse; with no fuse you will blow something else [unless you’re dealing with very small currents and voltages].
Which terminal of the battery is connected to the bulb?
The negative terminal of the battery is connected to a bulb and positive terminal of the battery is open. We know electrons flow in the negative terminal, so electrons are entering the bulb.
