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.
举一反三
- The value of drain current is always （ ） the value of the short circuit drain current IDSS for a given JFET.
- Digital multi-meter cannot measure ( ) when the measured circuit is working. A: voltage B: current C: resistance D: None of the above
- With no resistance(电阻) in the circuit(电路) the current(电流) would increase forever.
- When the secondary side of the electromagnetic current transformer is in normal operation, it is close to ( ) state. A: Overvoltage B: Open C: Short circuit D: Under voltage
- The input resistance of the whole multistage amplification circuit is the input resistance of ( )
