T / 2 6 root, multiply by 10. (sorry, I can't find the root)

An electric heater works normally when it is connected to 36V DC power supply with power of P. if it is connected to e = 36sin ω t (V) AC power supply with constant resistance, its power is______ ．

An electric heater works normally when connected to 36V DC power supply with power of P.P = 362r. If connected to e = 36sin ω t (V) AC power supply, the effective value of the power supply is u = 362v. If the resistance of the electric heater remains unchanged, its power is p '= P2

The voltage is 20V, and a resistor is 10ohm. Connect it with a 990ohm electric heater in series to calculate the current passing through the electric heater
It's a process

I = u / R total = 20 / (10 + 990) = 0.02A

In the circuit shown in the figure, DC generator e = 250V, internal resistance R = 3 Ω, R1 = R2 = 1 Ω, electric heater group is equipped with 50 identical electric heaters, each electric heater specification is "200V, 1000W", other resistances are ignored, regardless of the change of electric heater resistance with temperature? (2) When several electric heaters are connected, the output power of the generator is the maximum? (3) When several electric heaters are connected, the electric heater group heats the object fastest? (4) When several electric heaters are switched on, the power consumption of resistor R1 and R2 is the largest?

Calculated by P = UI, the rated current of the electric heater is I0 = Pu = 1000200a = 5a, and the resistance of each electric heater is r = UI = 40 Ω. (1) to make the electric heater work normally, the actual voltage at both ends of the electric heater must be 200V, so the main circuit current must be I = 10A. According to Ohm's law of closed circuit, I = ER1 + R2 + R + RN1 is obtained
