A low frequency generator is connected to an oscilloscope as shown in document 1. Given \(\sqrt{2}=1.4\), choose the correct answer and justify: By connecting this generator to an oscilloscope of vertical sensitivity Sv=200mV/div: a. we connect the input terminal to the positive terminal of the generator. b. the polarity of the connections is not important in AC mode. c. we connect the input to the negative terminal of the generator.

Understand the Problem
The question is asking to choose the correct statement about connecting a low frequency generator to an oscilloscope, given that the vertical sensitivity is 200mV/div and based on the provided image in Document 1. You need to justify your choice from the given options.
Answer
b. the polarity of the connections is not important in AC mode.
The correct answer is b. In AC mode, the polarity of the connections is not important because the signal alternates between positive and negative voltage. Therefore, the oscilloscope will display the signal correctly regardless of the polarity.
Answer for screen readers
The correct answer is b. In AC mode, the polarity of the connections is not important because the signal alternates between positive and negative voltage. Therefore, the oscilloscope will display the signal correctly regardless of the polarity.
More Information
In AC (Alternating Current) mode, the voltage signal continuously alternates between positive and negative values over time. Oscilloscopes are designed to display these alternating signals by showing the voltage variations with respect to time, regardless of the initial polarity of the connection.
Tips
The question can be confusing because it uses the term 'polarity' which usually applies to DC (Direct Current) circuits where the voltage is constant and has a definite positive or negative polarity.
