Electricity and Magnetism

Resistance is measured in a unit called the

• Ampere

• Coulomb

• Ohm

• Volt

The statement that current is equal to the voltage divided by the resistance is known as

• Einsteins law

• Faradays law

• Newtons law

• Ohms law

A path that allows only one route for an electric current is called a

• Parallel circuit

• Current circuit

• Current electricity

• Static electricity

What is the charge of a proton?

• Neutral

• Positive

• Negative

Current that does NOT reverse direction is called

• Direct current

• Alternating current

• Circuit current

• Magnetic current

The location of the strongest magnetic force is the

• Electromagnets

• Magnetic domains

• Magnetic fields

• Magnetic poles

Current that’s reversed direction in a regular pattern is called

• Alternating current

• Circuit current

• Direct current

• Magnetic current

Current is measured in units called

• Ohms

• Coluombs

• Volts

• Amperes

The region around a magnet where the magnetic forces act is the

• Electromagnetic pole

• Magnetic domain

• Magnetic field

• Magnetic pole
