Section 3-Electric Cirucits
Voltage and resistance
Resistance in an electric circuit increases the current in the circuit decreases.
If the diameter of the tube decreased resistance is greate.
Relationship among voltage current, and resistant
If the diameter increases, resistance is greater
a circuit that only has one path for electric current to follow.
a circuit that most more than one path for the electric current to flow.
Circuits control the movement of electric current by providing paths for electrons to follow.
the rate at which electrical energy is converted into other forms of energy.
The electric power is equal to the voltage provided to the appliance times the current that flows into the appliance.
cost of electric energy
power is that rate at which energy is used or the amount of energy that is used per second
cost of electric energy depends on the number of kilowatts hour
you experience an electrical shock when an electric current enters your body.
A current can enter your body when you accidentally become part of an electric circuit.
