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 … WebOct 10, 2016 · calculate resistance of the resistor network. You have two lines in parallel: 2.4 Ohm and (1.6 + 8) Ohm. Thus 2.4*9.6/(2.4+9.6)=1.92 Ohm. now when we know total … in a fast manner meaning
