For the direct current (dc) networks consisting of batteries, resistors (shown by the rectangular shapes), and light emitting diodes (LED’s) (shown by the triangular shapes) in Figures P14–20 determine the currents through each loop, in branches AD and BC in Figure P14–19, and in branch AD in Figure P14–20. What are the currents in each diode in these figures? If the desired current through the LED’s is to be not greater than 0.015 amp, are the standard resistors acceptable?
