i am unsure how to solve for the other parts of the table, the specfic equations for them using the information in for the first 3 columns.

Can someone run through me for the first number of resistors so i can then complete the whole table myself

Solution(s):

\(\large{ \begin{array}{|l|l|l|l|l|l|l|l|l|} \hline \mathbf{R}&\mathbf{I_n }&\mathbf{\Delta V_n}&\mathbf{Meas.I_{total}}&\mathbf{R_n}\;\Omega&\mathbf{Calc.I _{total}}&\mathbf{\Delta V_{total}}&\mathbf{R_{eq}}\;\Omega \\ \hline 1&5&15&*&3&5&15&3 \\ \hline 2&2.5&7.5&*&3&2.5&15&6 \\ \hline 3&1.67&5&*&3&5&5&1 \\ \hline \end{array} }\)

Notes:

* The measured current is determined (in a lab setting), using an amp-meter in series with the circuit. The measured current is unique to each circuit, and will typically vary up to \(\pm 20\%\) of the calculated value, depending on the tolerance of the resistors and the power supply.

R3 is three resistors in **parallel**. If the higher count resistor circuits use a combination of series and parallel resistors, it may be quite tricky to figure out.
