Presentation transcript:

Warm up 2/18 Explain Power What formula do you use to calculate the power used in a circuit? How can you know how much current will flow or how much voltage or resistance you will need in a particular circuit?

Parallel and Series Circuits How do series and parallel circuits differ?

What is the difference between a series and a parallel circuit? A series circuit has only one path for the electricity to travel. A parallel circuit has more than one path that it can follow.

Kirchhoff’s Voltage Law Over an entire circuit the energy out must equal the energy supplied by the battery.

Kirchhoff’s Current Law The current into a branch in a circuit equals the amount of current out of the branch.
