Finding Resistors Currents with Changing Resistance

32 replies · 7K views · last reply
Bump! Is anyone able to determine if I am correct or not? Thanks.
 
Hmm..I change my answer, so that when R increases, Req decreases. As for the other two...I say that the 12 ohm resistor would increase, and the 55 ohm resistor would decrease, is this correct?
 
Is anybody able to help me complete this problem? I would like to finish this possibly today. Thanks.
