____ states that the current through a circuit is directly proportional to the voltage across the circuit and inversely proportional to the resistance.

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

7.07 VPP is approximately equal to 2.5 VRMS.

____________________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.

____________________ materials have characteristics that fall between those of insulators and conductors.

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

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

What is the formula for total power in a parallel circuit?

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

A magnetic field around a conductor is a good indication that current is flowing.
