Consider the following figure. 7.00 0 4.00 0 9.00 0 R b (a) Find the equivalent resistance between points a and b in the figure. (R = 20.0 0) 18.18 (b) Calculate the current in each resistor if a potential difference of 74.0 V is applied between points a and b. I (4.00 0) = 4.07 A I (7.00 () = 1 055 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-Q resistor A 1 (20.0 0) 3.014 = X From the value of the current from a to b find the potential difference across the 20.0-0 resistor and then find the current through the 20.0-0 resistor. A I (9 00 0) = 4 06925 Need Help? Read It Master It
