in the combination of 3ohm res
in the combination of 3ohm resistor shown in the diagram there are two different parallel combination that in turn are in series with the middle resistor.
A. what is the resistance of each of the two parallel combinations?
B.what is the total equivalent resistance between points a and b?
C. if there is a voltage difference of 15v between points a and b what is the current flowing through the entire combination?
D. what is the current flowing through each of the resistors in the three resistor parallel combination?
