CHAPTER 35 BATTERIES AND ALTERNATIVE SOURCES OF
A battery of e.m.f. 20 V and internal resistance 0.2 supplies a load taking 10 A. Determine the p.d. at the battery terminals and the resistance of the load. P.d. at battery terminals, V = E – Ir = 20 – 10(0.2) = 18 V Load resistance, L V18 R I10 = 1.8 5.
Battery Internal Resistance
Battery internal resistance is the resistance that exists within a battery due to the flow of current through its electrolyte and other internal components. A battery internal resistance chart can be used to monitor the internal resistance of a battery and identify any potential issues before they become a problem.
