题目 有两个用电器分别标有“10Ω 1A”和“15Ω 0.6A”字样。把它们串联起来接到电路里时,其两端的电压不得超过__伏;若把它们并联起来接到电路里时,通过的总电流不得超过__安。 错解 标有“100Ω 1A”的用电器两端能加的最大电压U_1=I_1R_1=1安×10欧=10伏;标 Title There are two appliances marked with “10Ω 1A” and “15Ω 0.6A”. When they are connected in series in a circuit, the voltage across them must not exceed __V; if they are connected in parallel in a circuit, the total current passing through must not exceed __A. Misunderstanding The maximum voltage U_1=I_1R_1=1A×10Ω=10V that can be applied to both ends of the appliance marked “100Ω 1A”;
