When the following electrical appliances work normally, the current passing through is closest to 1a (A. household air conditioner B. household microwave oven C. television D. flashlight)

When the following electrical appliances work normally, the current passing through is closest to 1a (A. household air conditioner B. household microwave oven C. television D. flashlight)

Working current 1a, that is, the power is about 220W, select C
A. B is kW. D is obviously not that big, just a few watts

Among the following household appliances, the current closest to 0.5 A during normal operation is ()
A. Electric cooker B. air conditioner C. electric iron D. TV set

(1) The electric power of rice cooker, air conditioner and electric iron is about 1000W, and the current is about I = Pu = 1000w220 V ≈ 4.5a, so a, B and C are wrong; (2) in normal operation, the power of TV is about 110W, and the current is about I = Pu = 110w220 v = 0.5A, so D is correct; so D is selected
