What happens when a resistor is in-between two parallel resistors?
You can tell which direction the current will flow by removing the resistor. The left side will have (2/3) of 14V and the right (1/3) of 14V so the current will flow left to right (of course the voltages will change when the resistor is replaced.
You can also solve this for the actual current by finding the Thevenin equivalent of each side and then calculating the current.
It &quot;looks like&quot; a source of (1/3)14V with a source resistance of 2(1||2) = 4/3 ohms. Plus the 1 ohm R3 gives us 7/3 ohms, so the current through R3 can be calculated.
