Question

Which has higher resistance a 50 watt - 220 volt lamp or 25 watt - 220 volt lamp. Also calculate equivalent resistance in the circuit if both lamp are connected in parallel combination in the circuit.​

Answer 1

Answer:

1 is right one.

Explanation:

The formula to find the resistance with volt and power is R=p×v²,

CASE 1,here

p=50,. v=220 put these value in formula

R=p×v²

R=50×(220)²

R=2,420,000

CASE 2, here

p=25,. v=220 put these value in formula

R=p×v²

R=25×(220)²

R=1,210,000

HENCE HERE CASE 1 RESISTANCE IS HIGHER THAN CASE 2.
