For the direct current (DC) networks consisting of batteries, resistors (shown by the rectangular shapes), and light emitting diodes (LEDs) (shown by the triangular shapes) in Figures P14 -19 and 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 LEDs is to be not greater than 0.015 amp, are the standard resistors acceptable?
