Physics Quiz for Grade 1

What is common mode analysis?

• A process used to analyze the behavior of a circuit or system when input signals are kept constant

• A method used to analyze the behavior of a circuit or system when input signals are varied in opposite ways

• A technique used to analyze the behavior of a circuit or system when only one input signal is varied

• A technique used to analyze the behavior of a circuit or system when all input signals are varied together in the same way.

How can common mode analysis be applied in real life?

• Identifying the color of different fruits

• Measuring the temperature of different liquids

• Identifying and analyzing common factors or patterns in different situations or data sets

• Counting the number of stars in the sky

Explain the concept of difference mode analysis.

• A method used to combine two sets of data to identify the similarities between them

• A method used to analyze data in the same mode

• A method used to compare two sets of data to identify the differences between them

• A method used to compare two sets of data to identify the average between them

Describe an example of a common mode signal.

• A signal that is out of phase on both input terminals of a device

• A signal that appears simultaneously and in-phase on both input terminals of a device

• A signal that appears on only one input terminal of a device

• A signal that is only present in the output of a device

How do you calculate common mode voltage?

• By finding the average of the voltages on the two input terminals of the circuit.

• By counting the number of electrons in the circuit

• By measuring the resistance of the circuit

• By calculating the speed of light in the circuit
