For a silicon diode, if you apply a voltage of less than 0.7 V in forward biasing you will 

Which statement regarding an RC time constant is correct?

In a resistive AC circuit, it does not matter in which direction the current is flowing because power is assumed to have a(n) ____.

____________________allow the transfer of an AC signal from one circuit to another; the transfer may involve stepping up the voltage, stepping down the voltage, or passing the voltage unchanged.

When a diode is reversed biased, the depletion region of the diode

A step-down transformer could have a primary-secondary turns ratio of 4:1.

The ____ is used to determine the polarity of an electromagnet.

Ohmʹs law shows that current is directly proportional to the applied voltage and is inversely proportional to resistance.

Ammeters are always placed in series with the branch in which the current is measured.
