Suppose that bulb B1 in the figure is lit. If you momentarily press S2 at this time, what will happen? The bulb will blink. The bulb will dim. The bulb will go out. Nothing will happen. In the figure, which of the following actions will cause bulb B1 to light and remain lit? Pressing and holding S1, and then momentarily pressing S2 Pressing and holding S2, and then momentarily pressing S1 Pressing and holding both S1 and S2 Pressing both S1 and S2 momentarily Two electronics technicians are discussing the procedure that’s use to measure resistance in a circuit. Technician A says that to ensure an accurate reading, it’s important to start with the meter set to the highest resistance range and then decrease the range as necessary. Technician B says that to ensure an accurate reading, all power to the circuit must be turned off. Which of the following statements is correct? Only Technician B is correct. Neither of the two technicians is correct. Both of the technicians are correct. Only Technician A is correct. Refer to the wire resistance table. Technician A says that if 500 feet of number 18 wire and 1, 000 feet of number 22 wire are connected in series, the approximate resistance of the combined 1, 500-foot length of wire will be 20 ohms. Technician B says that if 200 feet of number 18 wire and 100 feet of number 22 wire are connected in series, the combined resistance of the 300-foot length of wire will be 3 ohms. Which of the following statements is correct? Only Technician A is correct. Both of the technicians are correct. Only Technician B is correct. Neither of the two technicians is correct. Look at the circuit diagram shown. What will happen in this circuit if switch S2 is pressed momentarily? Bulb B1 will blink momentarily. Nothing will happen. Bulb B1 will light up. Bulb B1 will go out.
