hmmm... Trying to solve this problem for a long time But I dont seem to have enough knowledge to do so :( Ok...I have a circuit with 2 switches. they are normal on/off switches. if switch one is on then circuit must produce an equivalent resistance of 100 ohms. If switch 2 is on then the circuit must produce an equivalent resistance of 0 ohms and 50 ohms otherwise. How can I achive this? I tried almost all combinations of resistors and stuff but it doesnot work. I dont know much about transistors either.

Thanks in advance K. Civilian
