# Why doesn't current increases when the voltage is increased

When connecting two batteries in series the voltage is increased. For example: Connecting two 5V batteries in series will produce 10V voltage but the current will be the same.

According to Ohm's Law V = IR the voltage is directly proportional to the current. Then why is the current not increases when voltage is increased?

• Because batteries are power sources not resistors, and therefore don't follow ohm's law. Also they don't have "a" current, they have a "maximum" current. – pjc50 Oct 22 '17 at 9:56
• Connecting two 5V batteries in series will produce 10V voltage but the current will be the same. In both cases the current will be 0 A (Zero Ampere) as no current will flow because you did not connect a load. It depends on the load how much current will flow. For simple loads like lightbulbs and resistors, the current will double when you double the voltage. – Bimpelrekkie Oct 22 '17 at 10:00
• @pjc50 So you mean - When the batteries are connected in series the just voltage is increased. There is no impact on current as it would be drawn as needed by the ckt attached to battery? – VVK Oct 22 '17 at 10:00
• When the same resistance is used in both situations the current does increase. – Wouter van Ooijen Oct 22 '17 at 10:27
• By means of resistors you mean any ckt that that consumes current. right? Oh no a resistor is just that, a resistor. Go read a book explaining what a resistor is. A circuit can behave completely different. You really need to get your basic electronics knowledge sorted out, I mean, read a book about it or somehow educate yourself. – Bimpelrekkie Oct 22 '17 at 11:50
