The basic contents of the postgraduate entrance examination outline include circuit model and circuit law, knowledge points: circuit and circuit model, reference direction of current and voltage; Electric power and energy, circuit components; Resistance element and capacitance element; Inductive element; Voltage source and current source, controlled source, Kirchhoff's law; Characteristics and energy relationship of capacitance and inductance.
The above are possible themes and possible contents. You can start learning from these aspects, which is definitely a cumulative process for English. I believe that hard work will have good results.
