Semester 2 Review

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 has more than one path to flow through

this circuit is?

• open

• closed

• parallel

• cutest one ever!

what kind of circuit is this?

• series

• parallel

• open

The force that pushes electricity through a circuit is called...

• resistance

• current

• voltage

• switch

In a closed circuit, how does the battery voltage affect current?

• as voltage increases, current increases

• as voltage increases, current decreases

• voltage does not affect the current

• if voltage exceeds current, then a short circuit develops

What is resistance?

• the flow of electrons

• a battery

• electric potential difference

• reducing flow of electrons

If two charges repel each other, the two charges must be

• positive and neutral

• positive and negative

• positive and positive

• negative and neutral

An object becomes charged when the atoms in the object gain or lose

• protons

• neutrons

• electrons

• all of these

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

• friction

• conduction

• convection

• induction

Charging by ___ occurs when electrons are transferred from one object to another by direct contact.

• reduction

• conduction

• induction

• friction
