Efficiency isn't the question. They just do different things. For example, if you look at a typical lighting circuit in a house, all the bulbs on a circuit are in parallel. They each have the same voltage across the bulbs.
If you rewired this so that the bulbs were in series then the voltage would be divided across each bulb and if one bulb burned out the others in series would get no current and would not light.
If you had two 60Watt bulbs in parallel in your house, each would draw 1/2 Amp. Add another bulb and it would draw 1/2 amp as well, for a total of three 60W bulbs drawing 1.5 amps from the power source. If the same three bulbs were in series there would be 40 Volts across each one with a current of 1/6 amps per bulb. Hence each bulb would be about 1/3 as bright as in the parallel circuit.
p.s. is series not cseries
Parallel circuit
parallel circuit.
Any circuit that even has more than one branch is a parallel one.
A parallel circuit is :)
A circuit that has more than one path for the current to flow is a parallel circuit. The circuit must have two or more paths to be considered parallel. A circuit that has only one current path through multiple components is a series circuit.
If a 'parallel' circuit has more than one load in its (not "it's"!) branches, then it is not a parallel circuit, but a series-parallel circuit! To resolve the circuit, you must first resolve the total resistance of the loads within each branch.
Generally, a circuit with multiple paths is called "parallel" because of the structure of the wiring involved. Parallel circuits have identical voltage on all paths, while current through each path is variable; whereas series circuits, having only one path, has constant current, but variable voltage.
a parallel circuit has 2 or more paths.a series circuit has 1 path.a parallel circuit is better for homes and school
Depends on what circuit you're refering to, a parallel circuit has parallel lines because it allows for voltage to pass through the circuit, giving more power.
In a parallel circuit, there are two or more branches connected to the voltage source, providing multiple paths for the current to flow. Each branch forms a separate circuit, but they share the same voltage source.
Is a parallel circuit whit 2 or more wires
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
