. Determine the resistance (in ohms) of a 14 m long circular wire when the diameter and the conductivity of the wire are 0.6 m and 12 mho/meter respectively.

If an open capacitor is checked with an ohmmeter, the needle will:

The ampere is the unit of resistance.

The formula for finding voltage when resistance and current are known is V = I/R.

Materials with a low retentivity do not retain a magnetic field very well.

Hysteresis is the number of lines of force per unit area in a magnetic field.

A magnetic field is made up of flux lines.

1. Lenz's law defines the polarity of the induced voltage.

When the speed at which a conductor is moved through a magnetic field is increased, the induced voltage
