Question

A) Determine the current in the starter B) Determine the current in the dead body R=2.01 r=0.08

A dead battery is charged by connecting it to the live battery of another car with jumper cables (see figure). (Take R = 2.01 and r = 0.08 2.) Starter 9V 10V Live Dead battery battery Ignition switch (a) Determine the current in the starter. (Enter your answer to at least one decimal place.) 1.2*10**3 x Your response differs from the correct answer by more than 100%. A (b) Determine the current in the dead battery. 2.7 x Your response differs from the correct answer by more than 100%. A Need Help? Read It Submit Answer Practice Another Version

Answer 1

using kVL in left loop

(0.01 + 2.01) i1 + 2.01 i2 = 12 - 10

2.02 i1 + 2.01 i2 = 2.... (i).

using kVL in right loop

2.01 i1 + 2.09 i2 = - 10... (ii)

solving (i) and (ii)

i1 = 1.336* 10^2 A

i2 = 1.333* 10^2 A

=======

current in starter = i2 = 1.333* 10^2 A

current through dead battery= i1 + i2 = 0.33 A
