Name: ___________________________
• Static Electricity: build up of charges that pass ________________ to
another object
• Electric Current: _______________________ of charges through a
conductor
Objects can acquire a static electric charge through:
1) Friction (when an object whose electrons are _________________ rubs
against another object)
2) Conduction (when an object with an excess of electrons
_________________ a neutral object)
3) Induction (a neutral object acquires a charge from a charged object
______________________________________________)
 Explain Induction
 Explain conduction
Electricity is the flow of __________________ (-)
Charges (-) flow from _______________ voltage areas to ______________
voltage areas
– Voltage is like electrical pressure that ________________________
charges
– Voltage Difference: the push/pull that
______________________________________________________
and is measured in volts (V)
Circuit: _____________________________________________
• For changes to flow, the wire must always be connected in a circuit
Electric Current: the flow of charges through a ______________ or
any _________________.
Measured in _________________ (A=Amps)
What happens if we break the circuit?
What affects Resistance?
Current = _____________________
Series Circuit: the current has only ______________________ to flow through
 Draw a picture
Parallel Circuit: contains _________________________ branches for current to
move through
 Draw a picture
Fuse: a small piece of metal that melts if the current
_________________________________________
Circuit Breaker: contains a small piece of metal that
___________________________ when it gets _______________
bending causes a switch to flip and ______________________
