The binary representation of 27 is?

Given R₁ = 10Ω, R₂ = 12Ω, R₃ = 9Ω, and R₄ = 24Ω,
what is the total resistance of a series circuit if it used these resistors?

The full-adder circuit has # inputs, # outputs, and is made up of # half adders.

• 4 inputs, 3 outputs, 3 half adders
• 3 inputs, 1 output, 1 half adder
• 3 inputs, 2 outputs, 2 half adders
• 2 inputs, 1 output, 1 half adder

Given the half-adder circuit diagram where A and B on the left are inputs, which of the terminals on the right correspond to SUM (S) and CARRY (C) ?

• SUM is the terminal from the AND gate, and CARRY is the terminal from the XOR gate.
• SUM is the terminal from the XOR gate, and CARRY is the terminal from the AND gate.
• SUM is the terminal from the OR gate, and CARRY is the terminal from the NOT gate.

1. You can set ground / reference to any node in the circuit. Just take note that it should have a nonzero value.

2. What makes the statement above invalid?

• The statement is actually True.

• ground / reference

• Any node

• Nonzero

Write the formula for Ohm's Law.

In a short circuit, the current through the element/s is:

• Zero

• Nonzero

• Infinity / Undefined

• None of the Above

Imagine a circuit with three resistors in parallel, with values of 12Ω, 4Ω, and 3Ω, respectively. What is the equivalent resistance of the circuit?

Which logic gate is used to create the SUM output in a full-adder circuit?

• AND gate

• OR gate

• XOR gate

• NAND gate

In a digital circuit, what is the role of a NOT gate?

• To invert the input signal

• To amplify the input signal

• To add two input signals

• To multiply two input signals
