Spring Final Exam Review

Front

What is induction in the context of electrostatics?

Back

Induction is the process by which a charged object causes a redistribution of charges in a nearby neutral object, leading to the attraction between the two.

Front

What does an electric motor do?

Back

An electric motor converts electrical energy into mechanical energy.

Front

Why does a charged balloon stick to a wall?

Back

A charged balloon sticks to a wall because it induces opposite charges in the wall, which are closer than other charges, creating an attractive force.

Front

Where should an ammeter be placed in a circuit?

Back

An ammeter should be placed in series with the circuit to measure the current.

Front

Where should a voltmeter be placed in a circuit?

Back

A voltmeter should be placed in parallel with the component across which the voltage is to be measured.

Front

What is an incident ray in optics?

Back

An incident ray is a ray of light that strikes a surface before being reflected or refracted.

Front

Define conduction in terms of charge transfer.

Back

Conduction is the transfer of electric charge through a material due to the movement of electrons.

Front

What is the difference between electrical energy and mechanical energy?

Back

Electrical energy is the energy carried by electric charges, while mechanical energy is the energy associated with the motion and position of an object.

Front

Explain the concept of friction in electrostatics.

Back

Friction in electrostatics refers to the process of transferring charge between two objects when they are rubbed together, leading to one object becoming positively charged and the other negatively charged.

Front

What is discharge in the context of electricity?

Back

Discharge is the process of releasing stored electrical energy, often resulting in a flow of current.
