The power supply voltage is 5 volts, and each LED is rated at 1.6 volts and 20 mA. Calculate the dropping resistor sizes and power ratings: B) After doing this, a co-worker looks at your circuit and suggests a modification. Why not use a single dropping resistor for both LEDs, economizing the number of components necessary? Re-calculate the dropping resistor ratings (resistance and power) for the new design. Include the total power consumed by the circuit and the power delivered by the source.arrow_forward
