The negative sign of y shows that the current is flowing into the 8-V battery and not out of it. In other words, it is a charging current and not a discharging current. Current flowing in the external resistance = x + y =1.625 - 0.75 = 0.875 A . P.D. across the external resistance = 10 x
A battery is not connected to anything. Is there a voltage
So the voltage is always present in this open circuit and only reduces from current passing thru it''s internal resistance to an external resistance in a current loop. Batteries are voltage sources with an effective series resistance, ESR often neglected if ESR is <1% of load R, yet you expect battery voltage will drop by this ratio of ESR / (ESR + Rload).

How Electric Current Flows In A 12 Volt Battery: Basics Of Battery
For example, in a 12-volt battery circuit, connecting a light bulb provides a path for current. If the battery delivers 12 volts and the bulb has a resistance of 6 ohms, Ohm''s Law shows that the current would be 2 amperes (12 V / 6 Ω). This current enables the bulb to light up, illustrating how voltage drives electric current flow.

Battery voltage drop when high load is connected
Battery voltage drop when high load is connected. Hello, As you can see from following graphs the battery voltage drops when load is active and jumps back to an higher value afterwards.

Does Battery Voltage Drop Under Load
When a load is connected to a battery, the current flowing through the load creates a voltage drop across the internal resistance of the battery. This voltage drop leads to
Can A Battery Have Voltage But No Current? Easy
Test with a Load: Testing the battery with a load, such as a light bulb or a resistor, helps determine if the battery can deliver current under pressure. If the battery provides voltage but fails to power the load, it likely indicates the battery''s inability to provide current, suggesting internal damage or failure.

External circuit: When the battery is connected to a load (like a light bulb), electrons can travel through the external circuit. This flow occurs because electrons are
6 FAQs about [Battery light current when external load is connected]
Can a battery have voltage but no current?
Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.
What happens if a battery has no load?
No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged. Open Circuit Voltage: Measuring voltage in a circuit with no load gives the open circuit voltage.
Does a battery give a load if it's a current source?
Well... yes and no. The battery will try and give the load whatever it asks for not the other way round. This is true for any voltage source not just batteries (current sources will try and push a set current through a circuit but voltage sources will just sit there and do as they're told).
What is the current flow through a battery loop?
Le's assume the load resistance is 4.5ohm and battery voltage is 9v, so current flow through the loop is 2amp; for the same load resistance (not be changed in any variation of voltage and current), if the battery voltage is 18v the current flow through the loop becomes 18v/4.5ohm=4amp. if I am wrong please give me feed back.
Why is a battery a constant voltage source?
A battery is a constant voltage source, and that´s what it´s going to do: provide a constant voltage to the circuit, regardless of current. your battery never determine the amount of current throw to the load, rather the load resistance and operating voltage of the load determine the amount of current.
Why does a battery have no current?
No Current Flow: A battery may have voltage but not deliver current due to internal resistance or damage. High resistance can prevent current from flowing even if a voltage exists. No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged.
