Why does increasing voltage increase current? [duplicate]
This means if you have two fixed points, and increase the voltage between them, you must be increasing the electric field strength in the region between them. Since the electric field is stronger, it will exert more force on charge carriers in that area, accelerating them more strongly, and thus increasing the current between the points.

6 FAQs about [Increasing the number of battery cells will increase the current]
What happens if you add more batteries to a circuit?
Adding more cells (batteries) in series to a circuit increases the overall voltage supply in the circuit, therefore increasing the current, according to Ohm's Law. If two more cells (ie. batteries) are added to the circuit in a series (end-to-end), the current will increase.
What happens if you add more cells in a circuit?
Assuming you add more cells in series, the voltage will increase. If you don’t change the resistance of the circuit, this in turn will also increase the current. What happened when Volta connected the parts of his cells in circuit? An electric current flowed around the circuit. What kind of current is produced by dry cells?
How does the number of cells affect the current in a circuit?
The number of cells in a circuit directly affects the voltage, not the current. Current is determined by the resistance in the circuit and the voltage supplied by the cells. So, more cells mean more voltage, which can potentially increase the current flowing through the circuit. More cells = more available power. Power = voltage * current.
Why does the number of cells in a series arrangement increase voltage?
The reason behind this is that increasing the number of cells in a series arrangement increases the overall voltage supply in the circuit. According to Ohm's law, the current (I) in a circuit is directly proportional to the supplied voltage (V) and inversely proportional to resistance (R), given by the formula I = V/R.
Does adding more cells in series increase current strength?
Increasing the number of cells connected together in series increases the strength of the current in the circuit and the potential difference across the cells. Do more cells in series indicate more electrical energy in the circuit? This investigation will show that adding more cells in series increases the current strength.
Does the number of cells in a circuit affect current strength?
As the number of cells connected in series increases, so does the current strength.
