hi

i need to find the current in the circuit number 48 it should be 0.6 amps.
can someone explain me how to solve it.

thanks.

If you color-code the wires it should be easy to see that R1,R2,R3 are in parallel; R6,R7,R8 are in parallel; R4,R5 are in parallel.

hi

i need your help. i need to find the total resistance in the circuit the answer is 0.5 ohm.each resistor is 1 ohm. but i don't understand how they connected. can you teach me how to recognize the type of connection if they connected in series or parallel connection.
thanks.

Again, if you color-code the wires then it will be easy to see which resistors are shorted out.

i really get stuck.
this is what i got.
after redrawing the circuit.

If you color-coded the wires, you would not need to work so hard.
