    What defines electricity?

    It encompasses natural phenomena related to electric charges.

    What is static electricity?

    It results from the accumulation of electric charges on a body.

    How do conductors differ from insulators?

    Conductors allow charge movement; insulators do not.

    What happens during electrification by conduction?

    Charges redistribute between two objects in contact.

    What is the unit of electric charge?

    The coulomb (C) measures electric charge.

    What is the role of an ammeter?

    It measures the electric current in a circuit.

    What does Ohm's law state?

    Resistance equals voltage divided by current.

    What is the difference between series and parallel circuits?

    Series circuits have one path; parallel circuits have multiple paths.

    What is the function of a fuse?

    It protects circuits by breaking the connection when current is too high.

    What is the significance of Kirchhoff's first law?

    It states that current entering a junction equals current leaving.

    What is an electromagnet?

    A solenoid with a ferromagnetic core that enhances its magnetic field.

    What does a diode do?

    It allows current to flow in one direction only.

    What is the purpose of a capacitor?

    It stores and releases electrical energy.

    How does the electric field behave?

    It exerts forces on charged particles at a distance.

    What is the relationship between voltage and current in Ohm's law?

    Voltage is directly proportional to current through resistance.

    What happens if a bulb is removed from a series circuit?

    The circuit becomes open, stopping current flow.

    What is the effect of increasing the temperature on resistance?

    Higher temperatures generally increase resistance.

    What is the role of a transformer?

    It changes the voltage level in an AC circuit.

    What is the function of a switch?

    It opens or closes a circuit to control current flow.

    What defines a ferromagnetic substance?

    It can be magnetized and attracted to magnets.
