1. The problem statement, all variables and given/known data 2. Relevant equations parallel(two shared nodes in two sides), series resistor(one shared node between 2 resistors) 3. The attempt at a solution I can't identify the circuit to be parallel or series in order to get the equivalent resistance. how should I finish the question? ( correction: answer=6kΩ) as i will have exam few hours later... please help!!!! thanks!
