Which of the answer choices is correct when discussing Law of Charges?

• Energy can be converted but it cannot be created or destroyed

• opposite charges repel and like charges attract electrons

• Like charges repel and opposite charges attract electrons

• the speed that a magnet passes a conductor increases the voltage value

Of the answer choices what is not considered a factor in the strength of voltage to be produced?

• The number in turns in the coil of wire

• The strength of the magnetic field

• The speed at which the magnetic lines of flux pass through the coil

• the size of the conductor

what best defines this image?

• sine wave a graphical representation of current and voltage over time

• the sine wave, a graphical representation of what is happening to the voltage over time

• the sine wave

• a graph of voltage and time

Multiple Answers:

Which of the following is correct when discussing current and voltage rising and falling at the same time?

• purely a resistive circuit is achieved

• power factor is at 100%

• they are said to be in phase

• only in a purely inductive circuit is achieved

what are the three basic elements needed in order for a circuit to function properly?

• source, conductor, and load

• short circuit, open circuit

• series and parallel circuit

• voltage, amperage, and resistance

What defines a short circuit?

• where a load is bypassed

• a circuit that does not have a open point

• an uninterrupted circuit

• two conductors are provided, a phase and a neutral

Multiple Answers:

_{Series Circuits}

• have only one path for current to flow

• current is constant in the circuit

• have multiple paths for current to flow

• voltage is constant in the circuit

This shows a lineman in...?

• open circuit

• Series with the circuit

• parallel with the circuit

• short circuit

Multiple Answers:

parallel circuits

• have more than one path for current to flow

• voltage remains constant

• amperage remains constant

• has only one conductor and one path for current to flow

Multiple Answers:

Induction

• only occurs when a magnetic field expands and collapses

• coiling jumpers will cause this and also lead to line loss

• occurs when a conductor is moved through a magnetic field

• coiling a conductor will increase this value
