    What are the steps to solve the Superposition Theorem?

    Replace all but one power source, calculate individual currents, then sum them.

    How does an ideal voltage source differ from a practical voltage source?

    Ideal has zero internal resistance; practical has some resistance.

    What happens to voltage across a practical voltage source as load resistance varies?

    Voltage changes with varying load resistance.

    What distinguishes a series circuit from a parallel circuit?

    Series has same current through all components; parallel divides current.

    What is the total resistance in a series circuit?

    Sum of all individual resistances.

    What is the total resistance in a parallel circuit?

    Reciprocal of the sum of reciprocals of individual resistances.

    How does a star connection differ from a delta connection?

    Star has 4 terminals; delta has 3 terminals.

    What happens to voltage across branches in a star connection?

    Voltage differs from supply voltage.

    What is the power consumption comparison between star and delta connections?

    Star consumes 1/3 of delta's power for equal resistances.

    What is the implication of an open circuit in a star connection?

    Remaining resistances see increased voltage.

    What is the implication of an open circuit in a delta connection?

    Circuit continues to function with half voltage across remaining resistances.

    What does Faraday's law of electromagnetic induction state?

    Induced e.m.f. is proportional to the rate of change of magnetic flux.
