A lamp is rated 240 V, 60 W. Determine the resistance of the lamp when lit?

Assessment: WAEC SSCE - Physics - 2022 (Objective) Subject: Physics

Question 1 Report

A lamp is rated 240 V, 60 W. Determine the resistance of the lamp when lit?
Answer Details

P = 60w, V = 240v, R = ?

P = V2R

: 60 = 2402R

→ R * 60 = 57,600

R = 5 57 , 600 60

R = 960Ω
