What happens if you connect batteries positive to positive?
Nothing. If the batteries are the same voltage you can then connect the positive terminals together as well as the negative and you will have a circuit with 2 batteries connected in parallel.
What happens if you connect two negative battery terminals together?
The wire will get hot. The battery will get hot. Depending on the chemistry of the battery, it may catch on fire and/or explode. The wire may melt.
What happens if you connect positive to negative on car battery?
Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries. The heat can melt internal and external battery parts, while the pressure from the hydrogen gas can crack the battery casing.
What happens when both positive and negative terminals of a cell are connected to the same terminal of a bulb?
Answer: electric circuit, the direction of current is taken to be from the positive to the negative terminal of the electric cell as shown in Fig. When the terminals of the bulb are connected with that of the electric cell by wires, the current passes through the filament of the bulb. This makes the bulb glow.
What happens if you put positive to positive?
The result of these two batteries connecting the wrong way could melt/damage either battery. If you have lead-acid batteries, which is the most common type of car batteries, hydrogen gas could be discharged. This happens when the casing of the battery cracks a bit because of the pressure of the hydrogen gas.
Will I get shocked if I touch the positive battery terminal?
You must complete an electric circuit in order to feel a shock. Merely touching the positive terminal of a 12V battery does not fulfill that requirement, unless some part of you simultaneously has a low resistance path to the negative terminal of that same battery.
What happens if only positive terminals of a circuit are connected?
If you connects only positive terminals and negative remains open then no current will flow as the circuit is open . case 2 if you connect positive terminal of one battery to positive terminal of other battery then it becomes a parallel citcuit.
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.
What happens when two batteries are charged at the same time?
If the load is a simple resistance, the current will not change, so the doubled power means that the two batteries will supply that current for twice as long before the available power is discharged.
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].
