The electric power of resistance R1 is P1, and resistance R2 and R! Are connected in series in the same circuit. The electric power of R2 is P2. It is known that P1: P2 = 36:5, and R1 > R2, then R1: R2 =? The electric power of resistance R1 is P1, and resistance R2 and R! Are connected in series to the same circuit. The electric power of R2 is P2. It is known that P1: P2 = 36:5, and R1 > R2, then R1: R2 =?

With the formula P = u / R, set the power supply voltage as up1 = u / R1. Later, R1 and R2 are connected in series, so P2 = UR2 / R1 + R2. Because P1: P2 = 36:5, U / R1: UR2 / R1 + R2 = 36:5, 5R1 + 5r2 - 26r1r2 = 0 (5r1-r2) (r1-5r2) = 0, R1: R2 = 1:5 or 5:1. Because R1 > R2, R1: R2 = 5:1
