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.

Electric Resistance describes how an electrical conductor (wire) opposes the flow of a current (flow of electrons) to overcome this opposition a voltage.

Example Example 1: An electric lamp is rated 110 W, 200 V. When the lamp is operated at its rated power and voltage, calculate a) the current flowing through.

Presentation transcript:

Bell Work: Current Electricity Electricity that flows is called ____ electricity. ( Resistance / Current / Voltage ) is supplied by the battery. Light bulbs would represent ( resistance / current / voltage ) in a circuit. The rate at which energy flows through the circuit is the ( resistance / current / voltage ). If you add more batteries, you will ( increase / decrease ) the current.

Phet Circuit Simulator

No batteries: no motion of electrons (energy) One battery: walk heel to toe Two batteries: walk normally Three batteries: how would you move now?

What happens to current when you increase the voltage? Are they directly or inversely related? What’s the other name for voltage? simple tracking transmitter

Two batteries: walk normally (slow) Add resistance: two chairs (you need to sit in the chairs and stand back up as you get to them) Add more resistance: 4 chairs

What happens to the current as you add resistance? Are they directly or inversely related?
