Voltage

[ebasappa]

Hey I just wanted to clear something up. Lets say there are 4 batteries all parallel to one another and each has a voltage of 7V. Now compare this to another circuit with only 1 7V battery. Assuming everything else in the circuit is the same between the two circuits, would they both supply a total of 7V to the entire circuit? (if that made sense haha...)

Multiple voltage sources add in series.

Multiple voltage sources in parallel supply the same voltage.

So basically, both of the circuits will supply 7V

Yes, except the one with more batteries will be able to supply higher current if needed. Say if you connect a very small resistor (which will draw high current), more batteries will be able to handle a smaller resistor.

No. Voltage is not supplied as it is a measure of potential difference.. Current is supplied and would depend on the internal resistance of the power source as well as it's voltage, so two batteries of equal voltage could supply different currents.

Ah I see, thanks for clearing that up! It makes much more sense.
