Find the resistance of a bulb, on which 60W and 120 V is marked. – InterviewSolution

1.	Find the resistance of a bulb, on which 60W and 120 V is marked.
Answer» <P> SOLUTION :P = 60W, V = 120 V We know P = VI `rArr(V_(2))/(R)(becauseI=(V)/(R))` `rArrR=(V_(2))/(R)=(120xxcancel(120))/(CANCEL(60))=240Omega.`
