Question

Please tell me now the answer of questions and it is from physics ​

Answer 1

Answer:

Explanation:

Explanation: See here time taken is same so energy will be power consumed on both

Take I =3 ampere and Potential

difference =60volts

Power (p1) = VI =3×60=180watt

Take I=1.5ampere and Potential difference= 120volts

Power (p2)=VI =1.5×120 = 180 watts

So P1 =P2

P1/P2 =180watts /180 watts = 1
