• 如果元件材料发生击穿全部电压都会安培计输入端,从而可能将其损坏

    If the component or material breaks down, all the voltage would be applied to the ammeter's input, possibly destroying it.

  • 使用分流型安培计(2 -49)时,输入电容电流测量影响电压测量时类似

    The effects of input capacitance on current measurements using a shunt type ammeter (Figure 2-49) are similar to those for voltage measurements.

  • 由于安培计电压可以忽略,所以所有测试电压出现电阻R上。

    Since the voltage drop across the ammeter is negligible, essentially all the test voltage appears across R.

  • 这种电流的降低安培计内阻RM引起的,内阻产生了一个附加的电压称为输入端VB)。

    This reduction is caused by the internal resistance (RM), which creates an additional voltage drop called the voltage burden (VB).
