[QUOTE="burnst14, post: 4616519, member: 487897"] [h2]Homework Statement [/h2] (a) Find the terminal voltage of a 12.0-V motorcycle battery having a 0.520 Ω internal resistance, if it is being charged by a current of 11.7 A. (b) What is the output voltage of the battery charger? [h2]Homework Equations[/h2] ΔV = ε - IR or V[SUB]terminal[/SUB] = ε - IR [h2]The Attempt at a Solution[/h2] ΔV = 12 - (11.7*0.52) = 5.916 = V[SUB]terminal[/SUB] This is incorrect. WebAssign also returned this information: [COLOR="Red"]"What is the sign of the current if it is flowing into the positive terminal of the battery? How is terminal voltage related to the internal resistance and battery emf?"[/COLOR] So I made it negative and submitted the response: -5.916 Still wrong. What am I missing? [/QUOTE]
