C9 Electricity and Circuits QUIZ

This is an example of a _______ circuit

• open
• series
• parallel
• square

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

The ampere is the charge transferred by a constant current of one ampere in one

second.

• coulomb

• volt

• joul

Joule = Ampere x Volt.

• Coulomb

• second

• ohm

The unit of measuring the electric charges is volt.

• coloumb

• second

• joul

The unit of measuring the electromotive force (e.m.f.) is the ampere.

• joul

• volt

• newton

Volt is the potential difference across the terminals of a conductor when the work done to transfer a quantity of charge of one coulomb between the two points is one second.

• volt

• ampere

• Joule

The value of the work done to transfer a quantity of electric charges of one coulomb between the two poles of this conductor is the------------

• a ohm.

• b. potential difference.

• c. current intensity.

• d. electric resistance.

The joule equals ----------

• a volt/coulomb.

• b. volt. coulomb.

• c. coulomb/sec.

• d. volt/sec.

The physical quantity which its measuring unit equivalent (joule/volt. second) is --------------

• a. current intensity.

• b. potential difference.

• c. work done.

• d. quantity of electricity.
