when two batteries of 3v and 6v are connected I Series what is the total voltage?
Answers
8 vol is the answer of this question
Answer:
Placing two batteries in parallel is an invalid arrangement, just like saying 3=6. This is because the 3v battery will maintain a terminal voltage of 3v irrespective of other circuit components and the 6v battery will maintain a terminal voltage of 6v irrespective of circuit configuration. As both sources are ideal, the terminal voltage of the parallel combination is nonsensical.
This is the same as placing two unequal current sources in series. This is also invalid. If one current source is 2 amp and the other is 3 amp, it is like saying 2=3 mathematically.
So voltage sources can only be connected in series and current sources can only be connected in parallel.
Finally, if a voltage and current source are in parallel then the current source has no effect and can be removed.
If a voltage and current source are in parallel the voltage source has no effect and can be removed.
Explanation:
Batteries connected in parallel will provide the same voltage as a single one, but last longer. When connected in series, the total voltage provided adds up, which means when you connect two 3V batteries in series, they will provide 6V in total and make the LEDs shine brighter.
