Electric Fields

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.

Front

What do electric field lines represent?

Back

Electric field lines represent the direction and strength of the electric field; they point away from positive charges and toward negative charges.

Front

What happens to electric field strength as distance increases?

Back

The electric field strength decreases as the distance from the charge increases.

Front

What is the relationship between electric field strength and charge?

Back

Electric field strength is directly proportional to the amount of charge; more charge results in a stronger electric field.

Front

What is the formula for electric field strength (E)?

Back

E = F/q, where E is the electric field strength, F is the force experienced by a charge, and q is the magnitude of the charge.

Front

What is the principle of superposition in electric fields?

Back

The principle of superposition states that the total electric field created by multiple charges is the vector sum of the electric fields created by each charge individually.

Front

What is the difference between conductors and insulators in terms of electric fields?

Back

Conductors allow electric charges to move freely, while insulators do not allow charges to move freely.

Front

How do like charges interact in an electric field?

Back

Like charges repel each other in an electric field.

Front

How do opposite charges interact in an electric field?

Back

Opposite charges attract each other in an electric field.

Front

What is the direction of electric field lines around a positive charge?

Back

Electric field lines around a positive charge point outward.
