When SCR is OFF, the current in the circuit is ________________?

Correct answer: B. Small leakage current

  • A. Exactly zero
  • B. Small leakage current
  • C. Large leakage current
  • D. None of the above

Explanation

An OFF SCR blocks the applied voltage but permits a small leakage current through its reverse- or forward-blocking junctions. It is therefore not an ideal open circuit with exactly zero current.
