Question
Problem 19.50 Correct The batteries shown in the circuit in (Eigure 1) have negligibly small internal resistances. Assume that 800 V and R 225 Part B Find the current through the 22 5 resistor Express your answer in amperes to three significant figures 1 0.134A MyAnswers Give Up Correct Significant Figures Feedback: Your answer 0.133 A was either rounded differenty or used a diferent required for this part Part C Find the current through the 8.00 V battery. Express your answer in amperes to three significant figures. 1 0.133 30.0 5.00 v Incorrect; Try Again; 5 attempts remaining
Explanation / Answer
Use Kirchoff's voltage law on the right loop
so, 5 - (22.5)(i1) - [i2 - i1](30) = 0
=> 5 - (22.5)(0.134) - [i2 - 0.134](30) = 0
=> i2 = 0.401 A
this is the current through the 8 volt battery.
