Start the PhET simulation "Circuit Construction Kit: DC - Virtual Lab". In the right control panel, select "Show Current" to "Convectional", and check "Values" option. In the left control panel, click $\square$ button to show symbols for electric circuit elements, such as conducting wire, battery, resistor, and switch. These symbols are used to draw a diagram for an electric circuit. Drag circuit elements to the blue area and build a circuit with two resistors $R_1$ and $R_2$ connected in series as shown in the right picture. Where, (). represents "Voltmeter" and (I) represents "Ammeter" in the right control panel. Voltmeter is used to measure the voltage $(V)$ across circuit elements. Ammeter is used to measure the current (I) flow through circuit elements. Setup the resistances of resistor $R_1=20.0\Omega$ and $R_2=30.0\Omega$. To setup the values of resistors, click on the resistor and change the value in the popup control panel. Click on the battery to setup battery output to $24.0\mathrm{V}$. Click "Switch" symbol to close the circuit and current will flow. The "Ammeter" is showing total current (I $I_{\text{Total }})$ drawn from the battery through two resistors. The "Voltmeter" is showing total voltage $\left(V_{\text{Total }}\right)$ across two resistors. Record these values in data table 1. \begin{tabular}{|l|l|l|l|l|l|l|} \hline$I_{\text{Total }}$ & $l_1$ & $l_2$ & $V_{\text{Total }}$ & $V_1$ & $V_2$ & $V_1+V_2$ \\ \hline & & & & & & \\ \hline \end{tabular}
