What is a circuit?

Circuit – a closed path through which ELECTRONS can flow. Think a about a race track. Can’t race with out a

complete track.

We can classify them in two ways.

Open – electrons won’t be moving

Closed – electrons will be moving

Wet and Dry Cell Batteries

Diagram from page 602 of Physical science textbook. Figure (A) is a dry cell battery and is a single cell. Figure (B) is a wet cell battery and has multiple cells. When we say cell we mean one cell, when we say battery we mean multiple cells.

Wet Cell vs. Dry Cell.

How their made.

Wet Cell - Lead Acid Battery

Dry Cell - Alkali Battery

Three Basic Units

The three basic units in electricity are:

Voltage (V) (measured in volts) Potential difference

Current (I) (measured in amps) Flow or number of electrons

Resistance (R) (measured in ohms) Tendency to oppose

Page 9: OH MY! Circuits, Batteries Volts, Amps, and Ohms.

Think Plumbing…(don’t write this!)

Voltage would be like water pressure…

Current is the flow rate…

Resistance is the pipe size...

Page 10: OH MY! Circuits, Batteries Volts, Amps, and Ohms.
Page 11: OH MY! Circuits, Batteries Volts, Amps, and Ohms.

Another Analogy

Page 12: OH MY! Circuits, Batteries Volts, Amps, and Ohms.

Ohm’s Law!

I = V/R This states that current is equal to the voltage divided

by the resistance.

This equation can be re-written to solve for any specific variable

Page 13: OH MY! Circuits, Batteries Volts, Amps, and Ohms.

Problem…

You have a tank filled with water connected to a hose that you are using to water the lawn…

What happens if you just increase pressure in the tank?

Remember……….. Ohms Law…..

Page 14: OH MY! Circuits, Batteries Volts, Amps, and Ohms.

Answer…

More water will come out of the hose

Electricity works in the same way! Increasing the voltage will make more current flow

Volt Meter

Volt meters are tools used to tell us how much voltage anything is producing…
