Q.	Magnetrons are microwave devices that offer very high efficiencies of about 80%.
A.	true
B.	false
Answer» A. true
Explanation: magnetrons are capable of very high power outputs, on the order of several kilowatts, and with efficiencies of 80% or more. but disadvantage of magnetron is that they are very noisy and cannot maintain frequency or phase coherence when operated in pulse mode.
