1.)An op amp requires the design equation Vout = 5Vin & 2Vref + AgVg. What is the value of Ag?
2.)The voltage dropout of a voltage regulator is 1.6 V. If a 16 V output is required, what is the minimum regulator input voltage?
3.) An H-bridge allows a 4 A current pulse to the drive motor. What is the average current if the duty cycle is 25% and the pulse frequency is 2 kHz?
4.) Why are capacitors used on voltage regulators?
