(a)
(b)
200 A 10.0 V 2.00 kW
   
No, there is only one independent equation, so only  can be found.
–0.120 V
 
(d) The assumption that such a cell could provide 8.50 A is inconsistent with its internal resistance.

(a) No, you would get inconsistent equations to solve.
(b)      . The assumed currents violate the junction rule.

(a) 1.58 mA
(b) 1.5848 V (need four digits to see the difference)
(c) 0.99990 (need five digits to see the difference from unity)
52
 
(c) Negative terminal voltage; negative load resistance.
