| 1. | There is no current through the galvanometer . 没有电流通过电流计。 |
| 2. | A current pulse is sent through the coil . 有一电流脉冲送入线圈。 |
| 3. | The electric current varies directly with the voltage . 电流与电压成正比。 |
| 4. | The current is the charge flow per unit time . 电流是每单位时间流动的电荷。 |
| 5. | The direction of the current is reversed . 电流方向倒换。 |
| 6. | The current lags behind the voltage . 电流滞后于电压。 |
| 7. | Wires transmit an electric current . 电线传导电流。 |
| 8. | The current i in all parts of the circuit is the same . 线路中各个部分的电流I都相同。 |
| 9. | In a word , the induced e. m. f. lags behind the current . 总之,感应电动势滞后于电流。 |
| 10. | The question was how could electric current make words ? 问题是,电流怎样才能变成言词? |
