What happens to the brightness of lightbulbs in a parallel circuit when you add more?
They stay the same
What happens to the brightness of lightbulbs in a series circuit when you add more?
They get dimmer
What type of circuit can we see in the picture?

In the International System, what is the unit of measurement for electrical power?
watts (W)
How do we calculate power (P)?
By multiplying the voltage of each component by the current that flows through it. P = V.I
