WebJul 5, 2016 · Alkaline, carbon-zinc and other primary batteries have relatively high internal resistance, and this relegates their use to low-current applications such as flashlights, remote controls, portable entertainment devices and kitchen clocks. As the batteries discharge, the resistance increases further. WebOct 25, 2024 · A low resistance produces low fluctuation under load or charge; a high resistance causes the voltage to swing excessively. Charging and discharging agitates the battery; full voltage stabilization takes up to 24 hours. Temperature also plays a role; a cold temperature lowers the voltage and heat raises it.
Weba common 9 volt battery provides a pretty high internal resistance to the flow of charges because of which the maximum current that you can ever draw from that is very tiny and so this is safe and you know we can let kids play with that on the other hand if you take a car battery which is just 12 volts not that much difference compared to this … WebThe battery voltage is determined by the internal resistance and output current. For example, suppose we have a battery electromotive force of E 0 10 V. The battery's …
