The lower the battery voltage the greater the current
Why does voltage reading increase the greater the resistance load?
So the lower R4 and R5, the more current, and therefore the more voltage loss in R1, which means less apparent voltage on the battery. Another way to see it is that you have 2 resistors in series (R1 and {R4, R5}). You split the voltage of the battery (10V) into the 2 resistors : the bigger resistor in proportion gets the biggest share.

8.3: Ohm''s Law
Ohm''s Law. The current that flows through most substances is directly proportional to the voltage (V) applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: [I propto V . label{20.3.1}]
How to Pick the Right Voltage Regulator(s) for Your …
Probably more than 90% of products require a voltage regulator of some kind, making them one of the most commonly used electrical components. Unless you''re able to run everything directly off battery voltage or an …
Why does increasing voltage increase current? [duplicate]
The floor is associated with a lower (gravitational) potential energy than the shelf. ... more charges (so more coulomb''s), moving from one point to the other per second. This is what we call current. In short: Voltage represents the electric forces on a charge, which in turn means higher current. ... How does more voltage (greater potential ...
Battery Internal Resistance: A Comprehensive Guide
This current flow, combined with the battery''s internal resistance, causes a voltage drop. The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a …
21.2: Electromotive Force
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).
Voltage, Current, Resistance, and Ohm''s Law
through a wire or the voltage of a battery sitting on a table. Even the lightning in the sky, while ... Because the resistance is greater, and the voltage is the same, this gives us a current value of 0.5 amps: So, the current is lower in the tank with higher resistance. Now we can see that if we know two of the values for Ohm''s law, we can ...

When current flows from a battery, does voltage decrease?
Applying Kirchhoff''s current law, you can check it for yourselves. No matter your circuit and its operating conditions, the current going out of the battery should be equal to the current going in. The voltage only changes because the chemicals inside the cell are changed slightly and not because of a change in the number of electrons.

What is Battery Voltage? Why the Voltage of Your Battery Matters
Lithium batteries, for example, typically have a voltage of 13.6V when fully charged in a 12 volt battery, while lead-acid batteries usually have a voltage of 12.7V when charged. The disparity between the voltages of each of these types of battery depends on the kind of chemical reaction occurring within the cells, which is the source of the voltage.

How is it possible to have high voltage and low current? It seems …
E=IR Your understanding that an increase in voltage should result in an increase in current is correct - swap out a 3v battery in a simple circuit for a 9v and you''ve jumped 3x current as well. High voltage/low current and vice versa is a TRANSFORMATION of what is ALREADY there - you are not swapping a battery (or any …

Why does voltage reading increase the greater the resistance load?
The greater the current, the more voltage you loose in R1, therefore the voltage across the real battery decreases. And if you decrease the resistance of the load, then you increase the current (if electrons have less trouble traveling, more will do so).
11.2: Battery Construction
The size of the cell is irrelevant to its voltage. To obtain greater voltage than the output of a single cell, multiple cells must be connected in series. The total voltage of a battery is the sum of all cell voltages. A typical automotive lead-acid battery has six cells, for a nominal voltage output of 6 x 2.0 or 12.0 volts:

Electric Circuits Review
A 5-ohm resistor would have a 5:1 ratio of voltage to current. This is a true statement since (2.5 Volt) / (0.5 A) is equal to 5.0 Volt/Amp. e. FALSE - The resistance of a resistor is the V/I ratio at that location. A 10-ohm resistor would have a 10:1 ratio of voltage to current.
