Question

Explain how a series circuit is different than a parallel circuit in regard to how the resistances (i.e. lights, appliances) are joined together. Then explain if it is more desired to have the wiring in a house based on a series circuit or a parallel circuit and why.

Answer 1

1. )

• at a single word you can say in series circuit current in the series resistances (appliances) are same but voltage across each resistaces are different(it depends on resistance value. if resistance is high then voltage drop across this high resistace are high vice versa .according to ohms law V=IxR )
• but in the case of parallel circuit voltage across each parallel resistace are same but current are different(it depends on resistance value if resistance is high then current will low vice versa .according to ohms law I=V/R)

if you connect resistaces (electrical loads ) in series then total equivalent resistace wiil offered will be the sum of these resistaces according to law R_total=R1+R2+........which means total resistance is increasing(cumulative effect) so current deliver from the source will reduce .

but if you connect same resistance above mentioned in parallel then total equivalent resistace offered to supply voltage source will reduce(by the equation 1_/R=1/R₁+1/_R2.+.......... ) and total current deliver from the source will high by the equation(oms law I=V/R) and also the voltage across each resistance are same

2)

99.9 % home appliances should be connected as in parallel because of company manufacture would mentioned the operating voltage(normal house voltage 230volt)   on that product .to get this voltage you should need to connect each appliance in parallel because of in parallel circuit voltage are same

if you connect these lights in series the voltage across each light will not get as company mentioned operating voltage so voltage are low and current are also low so power will reduce lamb will dim
