If you connect both poles of the same battery together, it will make a short circuit, because the electricity isn't going anywhere, just in one side and back to the other, it will cause whatever you used to connect them VERY hot. Electricity is a type of energy, and MOST energy (i say most because I am not 100% positive they have found an exception in this world) will have some connection to heat. But if you plan on doing it, get a lantern battery, one of the REALLY big batteries, and lay a paperclip on the top of it, or some other conductor on both poles of the battery, and back up. And if you are gonna remove it, wear an oven mitt :D
When you connect batteries in parallel, the positive terminals are connected together and the negative terminals are connected together. This increases the total capacity of the batteries, allowing them to provide more power for a longer period of time.
It depends how they are connected. If the terminals of two 12 volt batteries batteries are connected to the same circuit (in parallel) then there is no change in the flow of current- it will just last for twice as long a time. But if two opposing terminals of the batteries are connected to each other first and the free terminals then connected to the circuit (in series) then there would be a total voltage of 24 volts and twice as much current would flow. The two batteries would last for the same length of time as one battery on its own.
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.
There is addition of voltage. Dry cells have 1.5 volts irrespective of there size. if the cells are added as same polarity in series it will add if are parallel then voltage remains same
Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.
Nothing
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
If you put the batteries in a flashlight in the wrong direction, the electrical current won't flow properly, preventing the flashlight from turning on. It's important to insert the batteries according to the correct polarity indicated on the device to ensure it functions correctly.
A: Depends on meter leads voltage polarity and the diode itself orientation to these polarity. One way is should show a low impedance + to anode Reverse the diode it should be hi impedance
4V
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.
