What happen ????

Matter Electric charge Electric current Electric circuit

electric circuit complete, unbroken path through which electric charges can flow

A circuit Is a loop that electric current flow through it. A circuit cannot have any breaks. It must be a closed circuit.

A circuit diagram is a map of a circuit

Resistor Battery Conductor Switch

Resistor The volt (V): is a measure of the electrical force provided by an energy source. Batteries labeled : AA, AAA, C, and D each deliver about 1.5 volts. Ex:The small box-shaped batteries provide up to 9 volts. Resistor Battery Switch

amperes, also called amps Volt Ohms amperes, also called amps a measure of the electrical energy provided by an energy source measure the amount of resistance to an electrical current measure how much current moves past a given spot each second in a circuit

Resistor Battery Conductor Switch

Transform the electric energy into another form . Resistor Resistor Transform the electric energy into another form . The ohm (Ω) is the unit of measure for resistance to electrical current. A typical flashlight bulb has about 20 ohms of resistance. Battery Conductor Switch

Resistor Battery Conductor Switch

Conductor nonmetal Liquids and gases Metal Pencil lead Graphite Salt water Pure metal Mixed metals

Insulator help keep the electric charges inside the path way . What is the role of insulators such as plastic rubber and cloth covering wires and other conductor in a circuit Insulator help keep the electric charges inside the path way .

series circuit

Is the circuits that have more than one resistor on a wire. Electric series In a series circuit, the current must be able to pass through all the resistors.  

Suppose a series circuit has three bulbs . One bulb burns out . What will happen in the circuit ?

series circuit simple to build only 1 path for current to take advantage disadvantages simple to build if 1 light goes out- all go out more bulbs added- greater resistance

circuit diagram a map of a circuit, it shows parts and path of an electric circuit

If the switch is left open, what happens to the current? The circuit does not make a complete loop, so the current cannot flow.

circuit diagram a map of a circuit, it shows parts and path of an electric circuit volt a measure of the electrical energy provided by an energy source Ohms measure the amount of resistance to an electrical current. amperes, also called amps. Current is measured by how much charge moves past a certain spot each second. Volts are the measure of the electrical force provided by an energy source, Amps measure how much current moves past a given spot each second in a circuit.
