They are switches that enable one electric current to control the passage of another.(它們以開關的方式工作，使得一個通路中的電流可以控制另一通路中的電流。)

They found that protons do flow steadily across the nanotube, carrying an electric current.(他們發現，質子流穩定通過碳納米管，形成電流。)

The message wasreproduced at the receiving station on electrochemically sensitivepaper, which left a blue mark when an electric current was passedthrough it.(在電化學感光紙的接收站可將信息再次生成。當電流通過感光紙會留下一帶藍色的印記。)

Forcing an electric current across that junction causes the metal on one side to heat up, and the metal on the other side to cool down.(電流通過中間的調節器，使其一端的金屬升溫，并使另一端的金屬降溫。)

A household radiator absorbs energy in the form of electric current and releases it in the form of heat.(家用暖氣以電流的形式吸收能量，然后以熱量的形式將其釋放出去。)

Michael Faraday discovered in 1831 that an electric current flowing in a wire induces a secondary current in a neighbouring wire.(1831年，邁克爾·法拉第(MichaelFaraday)發現，在一根電線內流動的電流會在鄰近的一根電線內產生次級電流(secondarycurrent)。)

In the winter, ECC can be heated by passing an electric current through it, thereby preventing ice buildup.(在冬天，ECC可以通過電流加熱，從而防止結冰。)

An electric current has caused heat around the tip.(通過電流加熱針的尖端。)

If electric wiring is shorting out, shut off the electric current at the main box.(如果電線短路，請在主控箱切斷電源。)

In the case of harnessing vibrations, Chandrakasan and his colleagues use piezoelectric materials, which produce an electric current when subjected to mechanical pressure.(至于在約束振動上，切卓卡山和他的同事們使用了壓電體，在經受力的作用下，它可以產生電流。)
