Double Circuit Points:3 Consider the electric circuit in the figure below with the following parameters: E1= 24.00 V, 2= 12.00V, R1= 600 2, R3 = 300 oV What is the potential at point A? 2.40x101 v You are correct Your receipt no. is 164-5661 Calculate the current i1 0.0444A Hints: You will need both Kirchhoff rules The three currents are the three unknown quantities in the problem Use the first Kirchhoff rule to write a condition for the algebraic sum of the currents You will need two more equations You now nave' three eQusations and three unknownso solve the system. Submit Answer Incorrect. Tries 2/12 Previous Tries

Explanation / Answer

Applying KVL,

e1 - i1 R1 - i3 R3 = 0

600i1 + 300i3 = 24 ..... (i)

e2 - i3 R3 = 0

i3 = 12 / 300 = 0.04 A

putting in (i),

i1 = 0.02 A ..........Ans
