Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the governing laws?Ohm's Law (V=IR) and Kirchhoff's circuit laws (Current and Voltage Laws)
2. What is the key technological milestones?Voltaic Pile (1800), Transistor (1947), Integrated Circuit (late 1950s)
3. How does electricity travel in a circuit?Electricity moves through wires, following the path that the circuit makes, and it can go in a single line (series) or split into branches (parallel).
4. Why are Ohm's Law and Kirchhoff's Laws important?They help us know how much voltage, current, and resistance are in a circuit, so we can make sure it works safely and efficiently.

Electromotive Force (EMF): The energy per unit charge supplied by a source, driving current in a circuit.
Impedance: The total opposition to alternating current flow in a circuit, including resistance, reactance, and susceptance.
Semiconductor: A material with electrical conductivity between that of a conductor and an insulator, crucial for transistors and ICs.
