How does internal resistance affect voltage

WebPhysics questions and answers. (7\%) Problem 9: If you try to measure the voltage of a battery with a voltmeter connected in series, as shown in the figure, you won't get a completely accurate measurement because of the internal resistance of the battery. To see how large this effect is, consider trying to measure the terminal voltage of a ... WebThe internal resistance rises throughout the discharge, which is caused by a depletion of the electrolyte as it becomes more watery, which decreases its specific gravity. Lead acid batteries have a voltage drop from internal resistance from continuous high current discharge. Lithium-ion batteries:
