The correct answer is A. True.<\/p>\n
When measuring AC (Alternating Current) with a multimeter, it is important to maintain the proper polarity. This is because AC current reverses its direction of flow many times per second. If the multimeter is not connected with the correct polarity, the reading will be incorrect.<\/p>\n
To maintain the proper polarity, the red lead of the multimeter should be connected to the positive terminal of the circuit, and the black lead should be connected to the negative terminal. The polarity of the terminals is usually indicated by a positive (+) and negative (-) sign.<\/p>\n
If you are not sure which terminal is which, you can use a continuity tester to check for voltage. A continuity tester is a small device that emits a beep when it detects a voltage. To use a continuity tester, touch one probe to each terminal of the circuit. If the tester beeps, then the terminals are connected. If the tester does not beep, then the terminals are not connected.<\/p>\n
Once you have determined the polarity of the terminals, you can connect the multimeter and take your reading. Be sure to read the instructions that came with your multimeter to make sure that you are using it correctly.<\/p>\n
