Electricity. Circuit. Electricity is the flow of electric current in wires, motors, lights bulbs, and other devices Electric current carries energy great distances Electric circuits provides a path through which electricity flows.

If a material or object carries excess positive or negative charge it is electrically charged
Static electricity is the buildup of positive or negative chargesStatic Electricity
make higher voltage
Since voltage is measured from one point to another, the negative terminal of a battery has 0 volts.Measuring Voltage
Two bulbs are dimmer than just the one, because they each get only half the energy
In both circuits all of the 1.5 volt is used by the light bulbs
***No matter how many bulbs are present all of the voltage must be used in the circuit.
Voltage (volts, V)
Resistance (ohms, W)
Ohm’s Law can be used to calculate any of the three variables given the other two.
If the graph goes through the point (0,0) then you can calculate the resistance using R=V/I form of Ohm’s Law.Graphing
a given month.
Sometimes a larger unit of power is needed. A kilowatt (kW) is equal to 1000 watts
At the beginning, every charge has 3 volts of energy. As the charges move through the circuit, each light bulb is used by each bulb. All 3 volt of energy is
used by the circuit
