**Examples: Calculate resistance of conductor, and
calculate size of conductor**.

These are two examples. Example 1 is to calculate resistance of a metal with resistivity
1E-8 ohm-cm, and circle cross section (d=1E-5cm) and length=1cm. Example 2
is to calculate length of the conductor to have desired resistance (see figure
3)

In main menu, click Popular services>Semiconductor, then click Resistance
of conductor. Then choose cross section as circle from the list, give resistivity
1E-8 ohm-cm of the material, check Calculate I(V) & W(V). Figure 1 shows
the setup input.

Figure 1. Setup resistance calculation.

Click next step button to calculation page. Give diameter of 1E-5 and length of
1cm, and optionally operation voltage of 2V. Click calculate button to get resistance.
Figure 2 shows input to get the results.

Figure 2. Calculate resistance of conductor.

Example 2 is to calculate length of the conductor to have desired resistance 127.3ohm.
Input resistance 127.3, and diameter of 1E-5cm. If current and power calculation
is required, gives voltage applied. In my case, I do not want to calculate it and
leave the voltage input as blank. Bottom row of figure 3 shows the input. Click
calculate button to get results as shown in the 2nd row. In this case, the length
is obtained as 1 cm.
