WebThe real battery as an ideal emf V = 12 V in series with an internal resistance r as shown above left. The values for the resistors are: R 1 = R 3 = 39 Ω, R 4 = R 5 = 78 Ω and R 2 = 139 Ω. The measured voltage across the terminals of the batery is V battery = 11.41 V. WebMay 3, 2016 · If we connect a load across the battery, the voltage across the terminals drops. In this, we are measuring the voltage drop across a 4 Ω resistor. This drop in voltage is caused by the internal resistance of the battery. We can calculate the internal resistance if we take readings of the open-circuit voltage and the voltage across the battery ...
