Examples from the web for internal resistance
  • That, in turn, decreases the battery's internal resistance and improves its ability to store and deliver energy.
  • Apart from internal resistance, reformers face two further obstacles.
  • internal resistance and inductance limit the rate that energy can be released.
  • For internal resistance to become apparent, the battery must be connected to an external resistance to cause a current to flow.
  • The variable water level in the flow channel regulates the internal resistance of the fuel cell.
  • So removing one battery, also removes that battery's internal resistance, and hence the total circuit resistance also changes.
  • But it is necessary to consider that a conductor has internal resistance that opposes to the flow of electrons.
  • The internal resistance can then be calculated by dividing the change in voltage by the change in current.
  • During the first test, however, the internal resistance did not improve.
  • It is shown that the heat transfer is governed by the internal resistance of the dispersed phase.

internal resistance

(physics) the resistance of a cell, accumulator, etc, usually given as (E-V)/I, where E is the emf of the cell, and V the potential difference between terminals when it is delivering a current I
