Answer:B
What type of relay is used in applications where high-frequency switching is required?
A. Electromechanical Relay B. Solid State Relay C. Reed Relay D. Mercury Relay
Explanation: Solid-state relays are faster than electromechanical relays and can switch at high frequencies. They also have a longer lifespan and are less prone to mechanical failure. Reed relays are also fast but are not suitable for high-power switching applications. Mercury relays are not used in modern systems due to environmental concerns.
