在电容器短路的情况下，电阻器限制电流的大小。
The resistor limits the current in case the capacitor becomes shorted.
限流电阻(R)保护扫描卡在测试样板被短路时不被损坏。
The current limiting resistors (r) protect the scanner CARDS from damage if the test coupon develops a short circuit.
该电阻器的阻值要保证被测装置发生故障时的短路电流不会超过开关卡上任一组继电器的最大电流指标。
The value of this resistor is chosen such that, in the event of device failure, the short circuit current will not exceed the maximum current specification of the relays on either set of switch cards.
