With no resistance(电阻) in the circuit(电路) the current(电流) would increase forever.
举一反三
- The resistance value is infinite, the current passing through the resistance is always zero, and the voltage depends on the external circuit, then it is called as the short circuit state.
- 在电阻串联电路中，如果某一个电阻开路，则（ ）In a series resistive circuit, if a resistance is open, ( ) A: 总电流为0 the total current is 0 B: 总电阻为∞，the total resistance is ∞ C: 开路处的电压等于电源电压the opened-resistor voltage is equal to the supply voltage D: 开路处的电压等于0 the opened-resistor voltage is equal to 0
- electric circuit A: 电源 B: 电路 C: 电阻 D: 电流
- Digital multi-meter cannot measure ( ) when the measured circuit is working. A: voltage B: current C: resistance D: None of the above
- The input resistance of the whole multistage amplification circuit is the input resistance of ( )
