Answer 2

Tense and voice are grammatical concepts that relate to verbs in a sentence.

1. In the sentence "A capacitor is used for storing electricity," the tense of the verb is present tense, specifically present simple. This indicates that the action described by the verb "is used" is happening in the present or is a general truth.

2. In the sentence "A voltmeter measures the voltage and the potential difference in volts," the tense of the verb is also present tense, present simple. It describes a general truth or a habitual action.

Regarding voice, the verb "is used" in the first sentence is in the passive voice. The passive voice is used when the subject of the sentence is receiving the action rather than performing it. In this case, the subject "a capacitor" is the recipient of the action "is used."

The verb "measures" in the second sentence is in the active voice. The active voice is used when the subject of the sentence performs the action. Here, the subject "A voltmeter" is the one performing the action "measures."
