How do voltage and current affect a battery?

The higher the current, the more work it can do at the same voltage. Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for.

What is the relationship between voltage and current?

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 ∝V. I ∝ V. This important relationship is the basis for Ohm’s law.

What is the difference between voltage and current?

The higher the voltage, the more work the same number of electrons can do. Current = the number of electrons that happen to be passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage. Power = voltage x current.

What is the relationship between power and battery capacity?

The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.

What does voltage mean in a battery?

All these words basically describe the strength of a battery, but they’re all specifically different. Voltage = force at which the reaction driving the battery pushes electrons through the cell. This is also known as electrical potential, and depends on the difference in potential between the reactions that occur at each of the electrodes.

What is a voltage versus current plot?

A plot shows values of the voltage versus the current typical of what a casual experimenter might find. In this experiment, the voltage applied across the resistor varies from −10.00 to +10.00 V, by increments of 1.00 V. The current through the resistor and the voltage across the resistor are measured.
