it.

MSCERT Class 10 General Science Ch4 The Electric Spark

Answer 1

I = P/V

P=60W  ,  V = 220   I= ?

I = 60/220

= 0.27 A

Answer 2

Unit of Current= A( Ampere )......... A= p/v....... Here, in the ques. p (Power)= 60 W......... & v( Volt) = 220......So, A= 60/220=6/22=3/11= 0.27272727 A or simply 0.27 A.........
