Select the word that best completes the sentence. a tool or electrical system means intentionally creating a low-resistance path that connects to the earth.

Grounding

Explanation:

Grounding is secondary protection and used with the combination of primary protection. The purpose of grounding is to discharge the high voltage surges through a low resistance path to earth. These surges may be due to lightening and by coming in contact with the high voltage line. All electrical equipment is grounded for its protection. Grounding also saves humans from a shock because it prevents high voltage at the body of electrical equipment. Hence, Grounding will be the correct word.

(A) Equation will be

(B) RMS value of voltage will be 0.530 volt

Explanation:

We have given peak to peak voltage of ac wave = 1.5 volt

Peak to peak voltage of ac wave is equal to 2 times of peak voltage

So

Frequency of ac wave is given f = 3 kHz

So angular frequency = 2×3.14×3000 = 18840 rad/sec

So expression of equation will be ( As phase difference is 0 )

Now we have to find the rms value of voltage

So rms voltage will be equal to
