True False 2 A magnetic field consists of lines of force, which are more commonly referred to as flux lines. True False 3 Insulators are materials that don't readily give up electrons, thereby restricting the flow of current. True False 4 What is the wattage of a 120 volt household light bulb that has a resistance of 192 ohms and uses .625 amps? (P = I2 x R). 75 Watts 240 Watts 40 Watts None of the above 5 If the diameter of a conductor is doubled, the resistance is doubled. True False 6 The instantaneous value of a sine wave is the value at any particular time from zero to the peak value. True False 7 Electromagnetism is an interaction between electric current and a magnetic field. True False 8 Voltage is the rate at which energy is drawn from a source that produces a flow of electricity in a circuit. True False 9 Using the triangle that represents Ohm's law, the formula for calculating current is E = I x R R = E/I I = E/R 10 The voltage value as measured across each resistor or load, in a series circuit, is called Voltage rise Voltage drop Voltage peak Voltage fall 11 A(n)________is the basic unit of power, the amount of work accomplished when one volt causes one ampere to pass through a circuit. Watt Ampere Ohm Volt 12 Despite the fact that it has been positively determined that electron flow is the correct theory, conventional flow theory still dominates the industry. True False 13 The peak value of a sine wave occurs at the positive maximum and again at the negative maximum. True False 14 In the United States, Alternating Current (AC) is generated at ____________ hertz. 50 60 120 None of the above 15 The current flow in a parallel circuit divides itself between the branches back to the source. True False 16 Ohm's law is represented using a triangular diagram to determine the proper formulas to calculate voltage, current (amps) and resistance. True False 17 The three methods that voltage forces current to flow are direct current, alternating current, and pulsating current. True False 18 In a series circuit, when more than one resistance is in the circuit, the resistances are multiplied together to get the total resistance. (RT) True False 19 Single-phase is used where large blocks of power are required in commercial and industrial facilities. True False 20 Electrons can be freed by applying an external force, such as movement through a magnetic field, heat, friction, or a chemical reaction. True False
