Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFCurrent Reverser in Earth Tester:
An earth tester is an instrument used to measure the resistance of the earth and ground connections. The current reverser in an earth tester is an important component that converts the type of current supplied to the circuit.
Explanation of Options:
- AC to AC:
This option implies the conversion of alternating current (AC) to alternating current (AC) with possibly different parameters, but it does not align with the function of a current reverser in an earth tester.
- AC to DC:
This option implies the conversion of alternating current (AC) to direct current (DC). While some instruments may involve such conversions, it is not the primary function of the current reverser in an earth tester.
- DC to DC:
This option implies converting direct current (DC) to direct current (DC) with possibly different parameters, which is not the function of the current reverser in an earth tester.
- DC to AC:
This is correct. The current reverser in an earth tester converts direct current (DC) to alternating current (AC). This conversion is necessary to measure the earth resistance accurately and to avoid polarization effects that can occur with direct current.
Conclusion:
The current reverser in the earth tester converts:
4) DC to AC
