What happens if a battery has high internal resistance?
High internal resistance in a battery causes two main effects: it generates more heat than it should, and it reduces the battery's overall performance. The resistance within the battery causes some of the energy to be lost as heat, which can damage the battery and other components around it.
How does temperature affect internal resistance in a battery?
The magnitude and direction of the current passing through the battery affect internal resistance. Higher currents can lead to increased resistance due to factors like heat generation and changes in ion mobility within the battery’s components. Temperature Temperature variations play a critical role in internal resistance.
How does the internal resistance of a battery affect power delivery?
The internal resistance of a battery also plays a crucial role in power delivery. As current flows through the internal resistance, power is dissipated as heat. The formula P=I2RP = I^2RP=I2R quantifies this loss, indicating that power loss increases with the square of the current.
