| Abstract: | The electrotechnical experiment may result in DC current meter's point breakage and even DC current meter damage because some students often mistake DC current meter for DC voltmeter or select the wrong range. In this paper, an overcurrent protection circuit is introduced. The circuit can avoid the above errors. |
