We have a microcontroller (MCU) that operates at 3.3V. We want to connect a pushbutton switch to a digital input and a LED on a digital output. The pushbutton is normally open until pressed. The LED has a forward voltage of 2.3V at the operating current of 10mA. We want the input at the microcontroller to go high when the button is pressed. We want the LED to light up when the digital output is low Q5 Explain what two...

1. Circuit A contains a battery, a switch, and a resistor connected in series. Circuit B contains a battery, a switch, an inductor, and a resistor connected in series. Initially, the switch is closed in both circuits. How does the behavior of the current in circuit B compare with that in circuit A as both switches are opened at the same time? a. The current in circuit B decreases more slowly than that for circuit A since the inductor acts...

The switch 'S' in the circuit shown in the figure is connected to position 'a' for a long time. At t=0, the switch is thrown to position 'b'. With the switch now in position 'b', find the below-mentioned parameters: (A) - 20 % The frequency of oscillation of the LC circuit (derive any expression you deem necessary). (B) - 20 % The maximum charge that appears on the capacitor (no derivation required). (C) - 60 % The total energy the...

A.) Shown above are two different circuits. Each circuit is made
out a battery, a capacitor, a switch, and two resistors. All the
components (batteries, switches, capacitors, and resistors) are
identical in the above circuits. For both circuits, when the switch
is closed, the capacitors will get charged. Which of the following
is correct about the peak current in the circuit? Explain your
choice.
a) Circuit B has 4 times larger peak current than circuit A.
b) Circuit B has...

1. Sketch a circuit configuration using a MOSFET acting as a switch. 2. Design Challenge a) One common application of FETs is to use them as a switch. Use the circuit you completed above in (question 1) to create a switch with a MOSFET which can turn on and off the LED on your component board. This could be used with a micro controller to drive the LED. Sketch your circuit below, and briefly discuss your design and how it...
