**1. The problem statement, all variables and given/known data**

Each rectangle in the figures represents a resistor with resistance=2.9kΩ.

a) What is the net resistance of the circuit of Fig 1 connected to the battery? Each resistance has R=2.9 kΩ.

b) What is the current flowing into the junction c and the branch of ca from the battery?

c) If we replace the branch of bc with a 12V battery as Fig 2 shows and Vb>Vc, what is the current flowing into the branch of CA?

**3. The attempt at a solution**

a) Is the circuit in Fig 1 equal to that of Fig 3 as below?

Thank you.
