Pin chip Answer: A SIM stands for Subscriber Identity Module. The card contains information such as your phone number, your billing information, and your address book. It makes it easier to switch from one cell phone to another. Question: 179 When current flows through a wire, the following influences are present __________. A. amperes and ohms only B. voltage, watts, and ohms only C. voltage and amperes only D. voltage, ohms, and amperes Answer: D Voltage, ohms, and amperes are always present when current flows through a wire. Question: 180 Another name for cycles per second is __________. A. watts B. voltage C. hertz D. amperes Answer: C The number of times alternating current changes direction in one second is known as its frequency, which is measured in hertz. Question: 181 Which of the following materials usually has an electromagnetic-induction device in its core? A. brass B. silver C. aluminum D. iron Answer: D Iron is easily magnetized and demagnetized, so it works well for this device. Question: 182 How many diodes should you expect to find in a bridge rectifier? A. 0 B. 4 C. 8 D. 10 Answer: C A bridge rectifier is also known as a full wave rectifier, usually containing 8 diodes. Question: 183 Ohm’s law states __________. A. Voltage = Current x Resistance B. Amperes = Current x Resistance C. Voltage = Resistance ÷ Amperes D. Ohms = Voltage ÷ Current Answer: A Ohm’s law states that Voltage (V) = Current (I) x Resistance (R). All other answers are incorrect expressions of this law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
