Could you please give me the solution with steps of problem 28.35 and 28.36?

Fig. 28-17 In the circuit shown in Fig. 28-18, the ideal ammeter registers 2.0 A. (a) Assuming X its value. (b) Assuming XY to be a battery (with 2.0-2 internal resistance) that is being charged., tinu (c) Under the conditions of part (b), what is the potential change from point-Y to point-X? 6, 40 V 62 8.0 V 3.0 ? 6.0 ? OA 12? 2.0 A Fig. 28-18 The Wheatstone bridge shown in Fig. 28-19 is being used to measure resistance X. At balance, the current through the galvanometer G is zero and resistances L, M, and N are 3.0 ?, 2.0 ?, and 10 ?, respectively. Find the value of X. 256 ? /2 Fig. 28-19

Explanation / Answer

28.36

From the null condition of wheatstone bridge

X/N=L/M

X/10=3/2

X=15 ohm

So the value of the unknown resistance is 15 ohm
