physics
electric charges and current
the flow of charges is called electricity
e= 1.6*10-19
q=ne
i=qt
ahms
ammeter
ohms law
v=ir
the voltage is proportional to the electric current
resistance and the factors affecting resistance
opposition for the flow of charges
length
cross section
temperature
material
r= l/a
ohms m
arrangement of ressistors
series
r1 +r2 +r3 = rs
i is same
volt divides
maximum resistance
parallel
1/r1+ 1/r2+1/r3 = rs
minimum resistance
v is same i is different
potential difference
the work done to move the charge from one place to another
work done/charge
volt
voltmeter
higher potential to lower potential
heating affect
electrical power
