P2441101
Resistance, phase shift and power in AC circuits with digital
function generator
Self-inductance and resistor in series: tan phi
as a function of ν.
Principle
Work and power meter
Series circuits containing self-inductances or capacitances and
ohmic resistances are investigated as a function of frequency.
Measuring the electrical magnitudes with a work or power measurement instrument, real power or apparent power can be displayed directly.
Tasks
