The Key Differences Between Alternating Current (AC) and Direct Current
As the battery discharges, the voltage remains constant until it is depleted, at which point the output voltage begins to drop, although the polarity remains unchanged. In contrast, AC is the type of current that powers most household appliances in North America. When you plug in a light bulb, it is typically connected to an AC socket.

Battery Voltage: Debunking the Myth of Same Voltage in
There is a common misconception that all batteries have the same voltage and that this voltage remains unchanged throughout the life of the battery. However, this belief is not accurate. While it is true that batteries with the same voltage rating may have similar overall energy capacity, the actual voltage output of a battery can vary depending on various factors.

6 FAQs about [Battery voltage or current remains unchanged]
Does voltage decrease when current flows from a battery?
When current flows from a battery, does voltage decrease? I understand voltage to be a potential for electrons to be pushed through a circuit. However, in a battery, you have an electron build-up that creates the voltage. Once current begins to flow, electrons are now moving through the circuit.
What happens when a battery is drained?
Both effects occur as a battery is drained. The open circuit voltage goes down and the internal resistance goes up. Note that open circuit voltage is specifically measuring just the voltage the battery puts out with the internal resistance taken out of the equation.
What happens during a battery discharge process?
During the discharge process, the discharge current remains unchanged, the battery voltage decreases, and the discharge power also continues to decrease. The sample curve is shown in the figure below. ● Constant current and constant voltage (charging)
What happens if a battery reaches a cut-off current?
When the cut-off current is reached, the constant current constant voltage charging ends. Since the battery voltage fluctuates greatly after leaving the plateau period, if constant current charging is continued, the battery cannot reach the ideal full charge state.
Can a battery get complicated?
Usually, there is a significant temperature dependence too, both in terms of voltage and capacity. Yes, batteries can get complicated. Is it: V is the voltage of the battery, R is the external resistance or load, and I is the current passing through. then this has nothing to do with the voltage of the battery being lower as being consumed.
What happens if a battery is connected in series?
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
