Remember, a lower internal resistance indicates a healthier battery, while a higher internal resistance indicates a bad battery that needs to be replaced.
How do you calculate a battery's internal resistance?
This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing the amount of available voltage and current that can be delivered to an external circuit. The internal resistance of a battery can be calculated by measuring the voltage drop that occurs when a known current is drawn from the battery.
What happens if internal resistance is low?
When the value of internal resistance is low, the battery is able to carry a significant amount of current. On the other hand, a battery with high internal resistance can only carry a small amount of current. Fig.1 shows an example of the internal configuration of a battery.
How does internal resistance affect a battery's current-carrying capacity?
When the battery's internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V.
