Day 4 Parallel Circuits

Front

What 'flows' in a wire?

Back

Electrons

Front

What type of circuit connects components in parallel?

Back

Parallel Circuit

Front

What is the force of electricity that flows through a circuit, measured in volts?

Back

Voltage

Front

What device is like a fuse but made of copper and withstands overload for a short time?

Back

Current Limiter

Front

What is a major problem with series circuits?

Back

If one light goes down, they all go down!

Front

What is the unit of measurement for electrical resistance?

Back

Ohm

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law (V = IR)

Front

What is the total resistance in a parallel circuit with two resistors, R1 and R2?

Back

1/R_total = 1/R1 + 1/R2

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current increases.

Front

What is the purpose of a resistor in a circuit?

Back

To limit the flow of current.
