    What causes static electricity?

    Friction transfers electrons between materials.

    What happens to a material that gains electrons?

    It becomes negatively charged.

    What happens to a material that loses electrons?

    It becomes positively charged.

    Why is it called static electricity?

    Charges remain in one area and do not flow.

    What type of materials build up static electricity?

    Insulating materials like plastic or rubber.

    What occurs when two materials with the same charge are near each other?

    They repel each other.

    What occurs when two materials with opposite charges are near each other?

    They attract each other.

    What is required for an electric current to flow?

    A complete circuit and a power source.

    How do conductors differ from insulators?

    Conductors allow electron flow; insulators do not.

    What indicates a material is a conductor in a circuit test?

    The bulb lights up.

    What indicates a material is an insulator in a circuit test?

    The bulb does not light up.

    Why are metals good conductors of electricity?

    They have many free electrons.

    What is the function of a cell in a circuit?

    It provides energy to push electrons.

    What happens in a series circuit if one component fails?

    The entire circuit becomes incomplete.

    What is the unit of current?

    Amperes, abbreviated as 'A'.

    How is current measured in a circuit?

    Using an ammeter connected in series.

    What does voltage represent in a circuit?

    The energy transferred to an electrical charge.

    How is voltage measured?

    Using a voltmeter connected in parallel.

    What happens to voltage in a series circuit?

    It is shared among all components.

    What happens to the brightness of a bulb if another bulb is removed from a series circuit?

    The remaining bulb receives all the voltage, becoming twice as bright.

    What is the voltage across each bulb in a series circuit with two bulbs?

    Each bulb receives half of the total voltage.

    How does adding more bulbs affect a series circuit?

    It decreases the voltage per bulb, making them dimmer.

    What does a model represent in science?

    It helps visualize and understand complex ideas.

    How does a central heating system model an electric circuit?

    The boiler acts as the cell, and pipes represent wires.

    What happens to current in a series circuit?

    It remains the same throughout the circuit.

    What is the effect of adding more components in a parallel circuit?

    It increases the overall current due to more paths for flow.

    How does a parallel circuit differ from a series circuit?

    It has multiple paths for current, allowing independent operation of components.

    What happens to the voltage across components in a parallel circuit?

    The voltage remains the same across each component.

    What does high resistance indicate in a circuit?

    It makes it difficult for electricity to flow, resulting in a small current.

    How does resistance change when more bulbs are added to a series circuit?

    The total resistance increases, causing the current to decrease.

    What is the relationship between resistance and current in a parallel circuit?

    Lower resistance leads to a higher overall current.
