6 FAQs about [9V stacked battery short circuit current]
What happens if a 9v battery is short-circuited?
When a 9V battery is short-circuited, the current flowing through the circuit can be very high. This is because the voltage drop across the battery’s internal resistance is much less than the battery’s nominal voltage. As a result, a large amount of current can flow through the circuit, which can damage components or cause fires.
Is short-circuiting a 9V rectangular battery safe?
No, short-circuiting a 9V rectangular battery cannot be considered "safe" under any conditions. You're causing all of its energy to be dissipated in its own internal resistance, and it isn't designed to handle that kind of dissipation. While many batteries may tolerate this treatment without "violent" side-effects, there's no up-side to doing this.
How does a 9v battery work?
A 9V battery has an internal resistance of around 120 ohms. This means that when a current flows through the battery, there will be a voltage drop across the internal resistance. The voltage drop will be proportional to the current flowing through the battery and the internal resistance of the battery.
