Consider the following figure. 7.00 0 4.00 0 9.00 0 R (a) Find the equivalent resistance between points a and b in the figure. (R = 18.0 n) 18.4 (b) Calculate the current in each resistor if a potential difference of 68.0 V is applied between points a and b. I (4.00 17 X = Use the potential difference between a and b and the equivalent resistance between a and b to find the current between a and b. How is that related to the current through the 4.00-0 resistor?A I (7.00 9.7 X = From the value of the current from a to b find the potential difference across the 7.00-0 resistor and then find the current through the 7.00-n resistor.A 3.7 I (18.0 X = You may have incorrectly assumed that the current through the 9.00-0 resistor and through the 4.00-0 resistor is also the current through the 18.0-n resistor. Reexamine the diagram.A I (9.00 7.5 X 1 ) Consider how the current through the 9.00-0 resistor is related to other currents you have calculated.A
