electricity Flashcards
electric charge
the amount of energy
static electricity
imbalance between proton and neutron charge
explain BF
/
why is atom neutral?
atom has equal amounts of proton and neutron, so they will cancel out eachother
voltage
how much energy electron have
current
flow of electric charge
resistor
opposition to the flow of electric current in circuit
buzzer
provide an audible alert or notif
wire
made of copper wire covered with plastic sleeve, copper is the lowest resistance, conducts electricity
ammeter
to measure current connected with the object measured
voltmeter
to measure voltage
resistor
reduce the current
fuse
to protect electrical equipment from excessive current
variable ressistor
dimmer switch for a lamp and volume control
properties of series
connected end to end, same current, current comes from positive side, if ressistance is greater current is smaller
properties of parallel
connected side by side, current divides
circuit
a complete pathway for electrons to flow
charge
property of a particle/object
electric circuit
path for electric charge to flow
series advantage
easy to connect & need less wires
series disadvantage
more components makes bulb dimmer & if one resistor break the whole series is turned off
parallel advantage
more devices does not decrease the current & if one resistor break the rest does not
parallel disadvantage
more complicated & need more wires
direct current property
solar cells & chemical cells
alternating current
flows back n forth, found in homes, generators produce AC current
static electricity found in
photocopiers, printers, spray painting, pollutant removers
Why when you brush your hair with a comb, the comb can attract paper?
