Question

Write down expressions of 2 ressistors connected in series and parallel

Answer 1

Answer:

1. if connected in series then 1/Req= 1/R1+1/R2+1/R3.....
2. if connected in parallel then Req= R1+R2+R3+....

Answer 2

The two advantages of ressistors connected in series of such combination are:

• The series circuits do not get heated easily.
• Any dry or flammable object placed near the series circuit will not catch the fire in case of overheating of the circuit.
