Question:

In the circuit shown in Fig. 28-18, the ideal ammeter registers 2.0 A.

(a) Assuming XY to be a resistance, find its value.

(b) Assuming XY to be a battery (with 2.0-Ω internal resistance) that is being charged, find its emf.

(c) Under the conditions of part (b), what is the potential change from point-Y to point-X? S-40V S-80V 3.0 92 -- 1-202 5-202 6.00 ---- 1292 Fig. 28-18 2.0A Y
