Question

To determine the value of the resistances of the lightbulbs, look for the POWER (watt) and VOLTAGE DROP (V=220V) on the label of your lightbulbs. Then, use the derived formula of power (R = V2 / P) to get the resistance of each lightbulb.

After getting the resistance of each lightbulb, compute the total and individual values of the resistance, current, and voltage using the process of solving resistors in circuit following the GAFSA (Given, Asked, Formula, Solution, and Answer) format.

Given:

V_T= 220V
P₁ = 2.5w
P₂ = 2.5w
P₃ = 2.5w
P₄ = 10w
P₅ = 5w
P₆ = 5w
P₇ = 5w
P₈ = 10w
P₉ = 6w
P₁₀ = 6w
