摘要: A circuit for measuring alternating current (a.c.) and direct (d.c.) in a conductor without breaking the is provided. modulated source coupled parallel with segment of to inject test current. synchronous demodulator also across separate voltage drop induced by from due conductor. The are measured voltmeter resistance flowing through can then be calculated.
