Network of Resistors Flashcards
two basic ways in which to connect more than two circuit components
series
parallel
Here, we have three resistors (labeled R1, R2, and R3) connected in a long chain from one terminal of the battery to the other.
what kind of circuit
series circuit
there is only one path for current to flow.
serie circuit
Each individual path (through R1, R2, and R3) is called a
branch
all components are connected between the same set of electrically common points.
parallel circuit
components are connected end-to-end in a line to form a single path through which current can flow:
series conncetion
when connected to a voltage source, V, the ___ is closed
circuit
what circuit have the same current?
series
formula of current in series connection
It = I1=I2= I3
applying ohm’s low in series circuit the formula for V is
V = V1 + V2 + V3
applying ohm’s law for series circuit, the formula for R is
Rt = R1+R2+R3
all components are connected across each other’s leads
parallel circuit
in a parallel network, the voltage is
VT = V1=V2=V3
applying ohm’s law in parallel circuit the current is
IT = I1+I2+I3
equivalent resistance in parallel circuit formula
1 / RT = 1 / R1 + 1 /R2 + 1/ R3
