Which of the following is a characteristic of insulators?

• They have loosely bound electrons

• They allow electrons to flow freely

• They cannot pass electrons between atoms

• They are primarily made of metals

What does voltage act as in an electrical circuit?

• A source of light

• A resistance to electron flow

• A pushing force for electrons

• A measure of electron speed

What is the unit used to measure the flow of electrons?

• Coulomb

• Watt

• Ohm

• Amp

How does resistance affect the flow of electrons in a wire?

• It decreases the wire's thickness

• It increases the speed of electrons

• It restricts the flow of electrons

• It has no effect

What generates a magnetic field in a wire?

• Applying a capacitor

• Wrapping the wire in a coil

• Increasing the wire's thickness

• Decreasing the wire's resistance

What role do transformers play in electrical circuits?

• They store electrical energy

• They adjust voltage levels

• They decrease resistance

• They convert AC to DC

What is the purpose of a capacitor in a circuit?

• To convert DC to AC

• To store and release electrons

• To generate light

• To increase voltage

What is the primary difference between AC and DC?

• AC flows back and forth, while DC flows in one direction

• DC is only used in batteries, while AC is not

• AC flows in one direction, while DC flows in two

• DC can be converted to AC, but not vice versa
