Electricity Flashcard (Static/Current and Circuits

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily. Examples include rubber, glass, and wood.

Front

Which material is considered a good insulator?

Back

Wood is considered a good insulator.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, providing a single path for current to flow.

Front

How many conductive paths does a series circuit have?

Back

A series circuit has one conductive path.

Front

What happens to a light bulb in an open switch?

Back

If a switch is open, the circuit is incomplete, and the light bulb will not light.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, providing multiple paths for current to flow.

Front

How many conductive paths does a parallel circuit have?

Back

A parallel circuit has multiple conductive paths.

Front

What is the effect of adding more resistors in series?

Back

Adding more resistors in series increases the total resistance of the circuit.

Front

What is the effect of adding more resistors in parallel?

Back

Adding more resistors in parallel decreases the total resistance of the circuit.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as V = I * R.
