The properties of electricity can be broken down into three fundamental aspects. They are:

• Pressure, Flow, Direction

• Positive, Negative, Resistance

• Voltage, Current, Resistance

• Watts Law, Continuity, Power

Which of the following is not a correct Ohm's Law formula?

• V = I x R

• I = V ÷ R

• I = R x V

• V ÷ I = R

Which is true in regards to Conventional Current Flow?

• Electrons flow from positive to negative.

• Negative charges will cease to flow.

• Positive charges will cease to flow.

• Electrons flow from negative to positive.

The kind of power source that has a steady supply of electron flow.

• Alternating Current

• Branch Current

• Direct Current

• None of the above

What are the two ways loads can be connected in a circuit?

• With either insulated or non-insulated terminal boards.

• Hardwired or bluetooth.

• There is only one way to connect loads in a circuit.

• In Series or Parallel.

A circuit can be considered in series, if ___________________________________.

• There is only one path for current to flow.

• There are multiple paths for current to flow.

• There may or may have no path for current to flow.

• There is no path for current to flow.

Through experimentation, it was discovered that a relationship between Voltage, Current and Resistance exist. This relationship is called what?

• Watt's Law.

• Ohm's Law.

• Kirchhoff's Law

• Polarity Law.

Solve for: I = ?

• 72 Amps.

• 0.5 Amps.

• 18 Amps

• 2 Amps

According to Ohm's Law, the current in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance.

• True.

• False.

What voltage is required to light a lamp of 10Ω, if the lamp has a rating of 2 Amps?

• 5V

• 20V
