Basic Electricity

A form of electricity where the flow of current is always in the same direction:

• voltage

• power

• alternating current

• direct current

The force which opposes and reduces the flow of electrical current is recognized as ________.

• power

• resistance

• electromagnetism

• frequency

A part of an electric circuit which converts electrical energy into another form of energy to do work is ________.

• load

• circuit

• source

• control

A part of an electrical circuit, consists of batteries, generator or a main electrical power which supplies electricity is called ________.

• control

• load

• source

• voltage

A law that states that current is directly proportional to voltage and inversely proportional to resistance is known as ________.

• PEC

• Law of Resistivity

• Kirchoff's Law

• Ohm's Law

In Ohm's Law, to find the unknown voltage in the circuit, the formula to be used is:

• E = I x R

• E = I / R

• I = E / R

• R = E / I
