Electricity and Magnetism

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where there is only one path for the electric current to flow.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases as more resistors are added in a series circuit.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for the electric current to flow.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases as more resistors are added in a parallel circuit.

How does adding loops of wire to a solenoid affect its magnetic field strength?

Back

Adding loops of wire to a solenoid increases its magnetic field strength.

Front

What is the Right Hand Rule in electromagnetism?

Back

The Right Hand Rule states that if you hold a wire in your right hand and point your thumb in the direction of the positive current, the direction your fingers curl indicates the direction of the magnetic field.

Front

What happens to the other bulbs in a series circuit if one bulb fails?

Back

If one bulb fails in a series circuit, none of the other bulbs will work.

Front

What is the effect of a magnetic field on a compass?

Back

When a compass is moved near a strong magnet, it points toward the magnet.

Front

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; electric currents produce magnetic fields, and changing magnetic fields can induce electric currents.

Front

What is a solenoid?

Back

A solenoid is a coil of wire that generates a magnetic field when an electric current passes through it.
