7. In a pure inductive circuit, the phase angle between the voltage waveform and current waveform will havephase shift * 180 deg O deg 45 deg O 90 deg 8. Why do we say the "voltage across" or "the voltage with respect to?" Why can't we just say voltage? * Voltage is a measure of electric potential difference between two electrical points. O It's an electrical cliche. The other point could be negative or positive. None of the above.
