Hvac Unit 12 Basic Electricity And Magnetism Study Guide Graded A+

As the diameter of a wire increases so does the resistance. {Ans: False}In a circuit with two or more resistances in a series, the total resistance in the circuit is the sum of the resistances. {Ans: True}Describe inductance {Ans: in a coil in an AC circuit the magnetic field opens/close called inductive reactance}A transformer has 10,000 turns of wire in the secondary and 100 turns in the primary. The transformer is connected to a line voltage of 120-volts. The output voltage will be ________ volts. {Ans: 12,000}An element in an electrical heating unit is applied to a 232-volt power supply. The current flow through the element is 19 amps. What is the resistance of the element? {Ans: 12 ohms}If five electrons combine with three protons, the net charge will be? {Ans: Negative}When checking a diode with an ohmmeter, when the meter leads are connected to the diode, the meter should show resistance. If the meter leads are reversed, it should show infinity. {Ans: True}If a conductor carrying electrical current is formed into a coil, the magnetic field amount the wire will? {Ans: Increase}If two light bulbs are wired in a series and
