It is that circuit where two or more electrical consuming devices are connected so as to provide as many parallel paths to the flow of current.
Characteristics of parallel circuit
a. As many parallel paths as there are devices.
b. Individual devices will get its full efficiency.
c. Breakage in one circuit will not affect the other circuit.
d. Current in each device is different according to the resistance of the device.
e. If the individual resistance increases the total resistance will decrease (1/R = 1/ r1 + 1/ r2 +1/ rn)
f. The reciprocal of total resistance is equal to the sum of the reciprocal of individual parallel resistances (1/R = 1/ r1 + 1/ r2 +1/ rn).
g. Individual conductance is inversely proportional to the individual resistance.
h. If two same value resistors are connected in parallel circuit the total resistance is the resistance of one resistor. And the total of parallel circuit resistance will be less than the least resistance in that circuit.
