Electric Current and Voltage in DC Circuits
Voltage and current are the building blocks of electronic circuits. Voltage is circuit is one in which the voltage and current periodically change direction and magnitude. The circuit''s voltage (V(t)) depends on time (t). Battery Voltage: Devices like cell phones, remote controls, and clocks use battery voltage.
Does battery voltage change based on voltage supplied to charge
Battery voltage will match the charging voltage while on charge as long as charging current can be supplied. Once off charge (disconnected) battery voltage may sag a little to ''rest'' voltage depending on battery type. If you charge a lead acid (car battery) at let''s say 14v, the battery will be at 14v while charging.
When a battery drains, does the current and/or voltage drain?
If the load has a fixed resistance, like the bulb in a torch, then the power output reduces with the voltage - the torch''s light will get gradually dimmer. Some electronics adjust the load to pull a constant current or constant power from the battery.
Whether a battery is a constant voltage source or current source
It''s a constant voltage source, the value of current being drained out of it depends on the load. A 1kw 12v motor will drain more current from the battery than a 0.5 kw 12v. The voltage value is constant, current changes according to the power required by the load.

6 FAQs about [Battery is out of power voltage and current changes]
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 when a battery is fully charged?
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
What happens if a battery carries a current?
When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.
What happens when a lithium ion battery is charged?
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
Why do older batteries deliver lower voltages than new ones?
