Consider a combination of five resistors showh in the following circuit diagram. In this diagram, the symbol of each rectangular box represents \( a \) resistor. The resistance for each resistor is indicated on the diagram. The voltage across the battery is \( 12 \mathrm{~V} \). In the circuit, the values of all the resistances are known. These resistances are: \( R_{1}=3.0 \Omega, R_{2}=6.0 \Omega, R_{1}=2.0 \Omega, R_{4}=6.0 \Omega, R_{5}=12 \Omega \).
In the following diagram, the first resistor is labeled by its resistance \( R_{1} \). And other resistors are labeled accordingly.
Calculate the electric current flowing through the first resistor (labeled by its resistance \( R_{1} \).) What should this electric current that flows through \( R_{1} \) be?
The electric current that flows through \( R_{1} \) is:
