there will be little or no change
Electric circuits with 2 terminals can be arranged in "series" or in "parallel". This applies to all 2-terminal circuits - including fundamental components such as resistors, capacitors, or inductors. The term "series" means that an electrical path in an existing circuit is broken and the circuit is connected to the 2 terminals of the break. The term "parallel" means that the electric circuit is connected between 2 existing terminals or nodes of the existing circuit.
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
In parallel connection all the positive terminals are connected with positive of the source and all the negative terminals are connected to negative of the source. Whereas in series connection one positive terminal is connected to the negative of another, like wise it goes on and finally the positive end is connected to the negative of the source.
Capacitors are said to be connected together "in parallel" when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors. The voltage (Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then,Capacitors in Parallel have a "common voltage" supply across them giving: VC1 = VC2 = VC3 = VAB = 12V
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
All residential loads are connected in parallel, so that they share the same supply voltage, which is necessary for them to develop their rated power outputs.
parallel
That is how you connect 2 batteries in parallel. Like terminals are connected together. With this arrangement you still just have 12 volts, but the amperage doubles. You should also see the 2 positive terminals connected together. If not, then you may have a combination of parallel and series.
Two toy electric trains running on the same track are connected in parallel because they both get energized from DC impressed across the two rails they ride on.
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
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.
-- Connect the cells in series. The two terminals of their series combination present a potential difference of 4 volts. -- Connect both lamps in parallel between the terminals of the series-connected cells.
