College physical circuit science draws the equivalent circuit diagram of the power supply as shown below and calculates the current.
Figure ①: First disconnect the required current branch. 3 Ω series 1A is regarded as a short circuit, and the two voltage sources are converted into current sources.

Figure ②: Three current sources are merged into one current source.

Figure ③: Current source is converted into equivalent voltage source.

Figure ④: Connect the disconnected 2 Ω and find the current I. ..
