No, it is not supposed to be 12/4 + 1. In the original problem, the total equivalent resistance of the parallel combination was 4 . The voltage across this combination (and thus the total voltage supplied by the source) was 12 V. According to Ohm's Law, the total current (I) is calculated as: I = Total VoltageTotal Equivalent Resistance I = 12 V4 I = 3 A Adding +1 to the denominator or the result would imply an additional 1 resistor in series with the parallel combination, or some other component not present in the original circuit diagram. Based on the image you provided, there was no such additional resistor. 3 done, 2 left today. You're making progress.
