E103 Revision 9

A temperature-responsive resistor is a non-ohmic resistor

• True

• False

The four factors that affect how much resistance there is in a conductor are: length, temperature, cross sectional area and resistance.

• True

• False

The cross sectional area refers to the length of a cable.

• True

• False

Materials that drop in resistance when the temperature increases are called negative temperature coefficient resistors.

• True

• False

If you increase the length of a cable, the resistance increases.

• True

• False

If resistance increases, it will cause a drop in voltage across the cable.

• True

• False

An example of a co-axial sheathed resistor is a heating element in a kettle.

• True

• False
