Find equivalent resistance, the current in R5, Voltage of R2 and power of R10.
Actually, I don't know if my attempt is right. So, you would point out where there are mistakes, pleased.
R10 and R11 are in parallel (I called this R1011), also, R6 and R7 are in parallel (R67). Then R1011 and R12 are in parallel (R101112), then R9 and R101112 are in serie (I called it R9101112). Then R9101112 and R13 are in parallel (R910111213), then R1, R2, and R910111213 are in serie( R12910111213) And so on, Until now my circuit its this:
Then are R5 and R3 in paralell? If this is right I can continue myself. Another question, how to get current in R5 and voltage of R2? Kirchhoff's Rules ?
