Which two ways does a transient voltage surge suppressor (TVSS) work? (Choose two.)

Question

Options

• AAbsorbs transient energy
• BShort circuits the energy to ground
• CCloses the circuit and stops the energy flow
• DCompensates for the voltage change with battery power

• A
  80% (24)
• B
  10% (3)
• C
  7% (2)
• D
  3% (1)

Explanation

A transient voltage surge suppressor works by absorbing transient energy (A) and by short-circuiting excess energy to ground (B) - these are the two correct answers for this "choose two" question. Devices like metal oxide varistors (MOVs) clamp overvoltage spikes by conducting the excess current safely to ground while simultaneously dissipating the remaining energy as heat. Option C is wrong because a TVSS does not interrupt the circuit - it allows normal current to continue flowing while only diverting the surge. Option D is wrong because batteries compensate for power loss or sags, which is the role of a UPS, not a surge suppressor.

Memory tip: Think of a TVSS as a pressure relief valve - it both bleeds off excess pressure to a safe path (ground) and absorbs the shock, rather than shutting things down or adding power.
