Question

Explain .

a) why is series arrangement not used for Domestic circuit.

b) Why are conductor of electric heating Devices ,such as bread toaster and

electric Irons ,made up of alloy rather than pure Metal​

Answer 1

using series circuit the voltes will be devide in all instrument.

for exp; 250 voltes current is coming in a house and there are four fan and 2 bulb in house then current will be divide in fan 50 - 50 voltes and in bulb 25 -25v

and using parrlel current will go eqal in all instruments.

Answer 2

in series large amount of current waste in the form of heat and give less efficienncy .

conductor of heating devices like bread toaster is made up of alloy because pure matel is good conductor of heat also so it will malt easily so alloy whose melting point is high as well as high resistivity property of alloy taken so that it doesn't melt and produce large amount of current.
