VerifiedInfrastructure and System Security

Which of the following devices is the least expensive power-protection device for filtering the electrical stream to control power surges, noise, power sags, and power spikes?

Explanation

A line conditioner filters and stabilizes incoming electrical power, helping control electrical noise, surges, spikes, and voltage sags. A surge suppressor does not provide the same broad power-conditioning function, and a UPS adds battery backup at greater cost.
