Problem 1: Consider a combination of five resistors shown 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 V. In the circuit, the values of all the resistances are known. These resistances are: R, =3.0 0, R, =6.0 0, R, =2.0 0, R. =6.0 0, R, =12 0. In the following diagram, the first resistor is labeled by its resistance R . And other resistors are labeled accordingly. R4 R1 R3 R2 R5 +12V Calculate the electric current that flows through the second resistor, which is labeled by its resistance R . What should the electric current that flows through R be
