Answer 1

Answer:

The following circuit diagram (Fig . 8.51) shows three resistors 2Ω, 4Ω and RΩ connected to a battery of e.m.f 2 V and internal resistance 3Ω. A main current of 0.25A flows through the circuit. (a) What is the p.d. across the 4Ω resistor? (b) Calculate the p.d. across the internal resistance of the cell. (c) What is the p.d. across the RΩ or 2Ω resistor? (d) calculate the value of R.Read more on Sarthaks.com - https://www.sarthaks.com/149419/the-following-circuit-diagram-fig-51-shows-three-resistors-2-4-and-r-connected-battery
