1The "Electron theory of Electrical Flow" states that:
- AElectrons move from Negative to Positive
- BProtons Move from Positive to Negative
- CNeutrons Move from Negative to Positive
- DElectrons move from Positive to Negative
2The Conventional Theory of Electrical Flow proved that electrical charges move from negative to positive
- ATrue
- BFalse
3Electrical current (or the flow of electrons) in a wire may cause:
- AFriction and therefore heat in a wire
- BThe opposite electrical charge to be induced in another material
- CA magnetic field around the wire
- DAll of the listed choices
4Which of the following tests on an energized circuit will give a reading of applied voltage?
- AAcross an open switch
- BAcross a load
- CAcross the course (-) and neutral (+) lines
- DAll of the listed choices
5If the voltage drops across a load in a simple circuit is not the applied voltage, this indicates:
- AThere is more than one load wired in series with the tested load
- BThere is more than one load wired in parallel with the tested load
- CThe load is faulty and should be replaced
- DNothing is the matter
6Which of the following statements is correct?
- AVoltage is always negative in an AC cricuit
- BHolding a wire in a magnetic field will induce a voltage in the wire
- CA single phase electrical supply has one applied voltage and one applied current
- DIt is impossible to determine the power delivered by an AC electrical supply
7Back EMF is an electrical term that means:
- ANegative applied voltage from the electrical supply
- BInduced voltage from the coil of an inductor that opposes applied voltage
- CPositive applied voltage from the electrical supply
- DA back log of current produced by a resistive load
8In a capacitive circuit, current leads voltage in an out-of-phase relationship
- ATrue
- BFalse
9A properly designed induction coil in an electromagnet will have very little current flowing through it when the electromagnetic force is not doing any work
- ATrue
- BFalse
10An ohmmeter reading between a good solenoid coil and the solenoid casing will indicate
- AInfinite resistance
- BMeasurable resistance
- CZero resistance
- Dfluctuating resistance
11Which of the following statements is not correct?
- AA battery connected to a coil will create an electromagnet
- BAlternating current is required for a transformer to function
- CA building and collapsing of an electromagnetic field is required for a transformer to function
- DThe induced voltage is exerted in the same direction as the applied voltage in an transformer
