SUMMARY
The discussion focuses on calculating the voltage drop required for a 60W light bulb to operate like a 50W bulb during a brownout. The relevant equation is P=V^2/R, where resistance remains constant. The user proposes using P=(V-h)^2/R to represent power under a small voltage drop, but struggles to eliminate the variable h. A suggested approach is to use P_2 = V_2^2/R, where P_2 equals 5/6 of P_1, to find the ratio of V2 to V1.
