You are taking a reading from an open switch and are getting an unpredictable reading. This can be fixed by: [Choose all that are correct] O Installing a pull-up resistor connected to ground Setting the Arduino pinMode() to INPUT Setting the Arduino pinMode) to OUTPUT O Installing a pull-up resistor connected to power Setting the Arduino pinMode() to OUTPUT_PULLDOWN Setting the Arduino pinMode() to INPUT_PULLUP

a) Figure 3 illustrates a thyristor phase control circuit and associated waveforms. Describe the function of the control element in the circuit towards the output at the load. Identify the best-suited application to describe the control circuit. Lamp Load VAC SCR r 9 8₁ Conduction MM h 18₂ h Gate Trigger Pulse

Problem 4: Implementation of 1, 2 and 4 quadrant switches.Explain the concept of 1, 2 and 4 quadrant switches in power electronics. Describe how these switches work and in what situations they are used. Design a simple circuit that uses each type of switch.
