What happens if you connect two positive battery terminals together with the negatives to ground?

That is called a parallel connection and will double the power if the batteries is the same size and the same voltage, the voltage will be the same as one battery, so if it is two 12 volt batteries the voltage will be 12 volt. It is dangerous to connect two batteries of different voltage in parallel like a12 volt and a 6 volt the 6 volt will then draw current from the 12 volt and it can overheat and even explode.

∙ 9y agoIf you connect two negative terminals to ground in a circuit it will not pass the current. There has to be connection to the positive terminal for power supply to flow.

How does a torch work for kids?
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
Why potential difference is necessary to produce current in a circuit?
AnswerPotential difference, voltage, is a force that will cause electrons (negative charges) to move if they can. Voltage is the motive power behind electron flow, and electron flow is the current. In a battery, we have voltage between (or across) the terminals from chemical energy inside. We don't have to have current flow to have the voltage. Some might think of voltage as "electrical pressure" because it is a force. That isn't a bad way to look at it. If we connect some wires and put a light bulb and a switch in series across the terminals of the battery, we have a circuit. If we close the switch, voltage, which was present all the time, will now cause electrons to flow through the wire and light the bulb. The battery has a positive terminal and a negative terminal. The positive terminal will take in electrons and the negative terminal will send them out. Current flows in only one direction. The potential difference created by the battery has energized the circuit and current flowed from the negative terminal of the battery, out through the circuit, and back to the positive one.
How does emergency light switch work?
An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off. One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation. note: The normally off is not use. And may be use for some purpose.
How the three phase rectification is achieved?
You achieve three phase rectification with a three phase rectifier. There is one in the alternator of you car. You have three windings, connected delta, so there are three terminals. Three diodes are connected to these terminals, anodes towards the terminals, cathodes common and connected to the battery. Three more diodes (for a total of six) are connected to the terminals, cathodes towards the terminals, with the anodes common and connected to ground. At any one moment of time, one winding provides voltage to cause two diodes to conduct, charging the battery. As the alternator rotates, the windings and the diodes take turns, effectively providing a three phase AC to DC power source to the battery. If you look closely, there is another set of three, smaller, diodes connected as well, anodes towards the terminals. These diodes provide power for the integrated regulator, but the six main diodes are large and heatsinked into the frame of the alternator.
What happens when you connect the car positive and negative battery terminals together Will this reset car computers?
If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.
What are the parts of a battery?

What is a positive terminal on a battery?
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
What causes hot positive battery terminals?
Dirty connection
It has a potential difference between the positive and negative terminals?

Which side of the battery terminals is positive on a 2006 Kia Sedona?
On the battery is marked - or +. The red cable is positive and the black is negative.
How are the terminals of a battery labeled?
Normally it is imposed on the battery case next to the posts. The larger post is positive.
