If an electric furnace is connected to a circuit with a voltage of 220 V and the energy consumed in 10 min is 6.6 times 10 quintic J, the electric power of the electric furnace is [] The current through it is [], and the resistance of the furnace wire is

Power P = A / S = 660000 / 600 = 1100W
Current I = P / u = 1100 / 220 = 5A
Resistance R = u / I = 220 / 5 = 44 Ω

When two pz220-100 bulbs are connected in series in a 220 V circuit, the total power consumed is——

50w
Because the resistance is doubled, the voltage remains unchanged, the current becomes half of the original, and the total power becomes half of the original

Li Gang wants to make an electric heater by using two resistance wires with resistance values of R1 and R2 (R1 > R2). In order to make water of the same quality rise to the same temperature in the shortest time, which of the following four design schemes is the most feasible? （　　）
A. Two resistance wires in parallel B. two resistance wires in series C. separate resistance wire with resistance R1 D. separate resistance wire with resistance R2

The total resistance is the smallest when two resistors are in parallel, so the electric power is the largest when two resistors are in parallel, so it takes the shortest time for water of the same mass to rise to the same temperature
