Series and Parallel

Front

What is a simple series circuit?

Back

A simple series circuit is one where electricity flows along one pathway.

Front

What is a parallel circuit?

Back

A parallel circuit has more than one path for electricity to flow.

What happens to the velocity of a ball thrown upwards as it moves against gravity?

Back

As the ball moves upwards, friction and gravity decrease the ball's velocity.

Front

What is a disadvantage of using a series circuit?

Back

If one light goes down in a series circuit, all lights go down.

Front

How do electric and gravitational forces differ in terms of object size?

Back

The gravitational force applies to any sized object, while the electric force only acts on charged particles.

Front

What is the total resistance in a series circuit with three resistors of 2 ohms each?

Back

The total resistance in a series circuit is the sum of all resistances: 2 + 2 + 2 = 6 ohms.

Front

How does the voltage behave in a parallel circuit?

Back

In a parallel circuit, the voltage across each branch is the same.

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

The formula for total resistance (R_total) in a parallel circuit is 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the effect of adding more resistors in series on the total resistance?

Back

Adding more resistors in series increases the total resistance.

Front

What is the effect of adding more resistors in parallel on the total resistance?

Back

Adding more resistors in parallel decreases the total resistance.
