Question

protection of electrical and electronic equipment from surges is accomplished by
a. shielding from electromagnetic fields
b. filtering out high - frequency currents and voltages
c. installation of surge suppressors
d. any or all of the above

a

b

c

d

Explanation:

To protect electrical and electronic equipment from surges:

• Shielding from electromagnetic fields (option a) can prevent surge - inducing electromagnetic interference.
• Filtering out high - frequency currents and voltages (option b) helps as surges often have high - frequency components.
• Installing surge suppressors (option c) is a direct method to mitigate surges.

Since all these methods contribute to surge protection, the correct option is d.

Answer:

d. any or all of the above
