1.3 Static and Current Electricity

What is resistance?

• Resistance is the opposition to the flow of electric current, measured in Ohms (Ω).

• Resistance is the measure of how much current flows through a conductor.

• Resistance is the ability of a material to conduct electricity without any opposition.

• Resistance is the force that pushes electric charges through a circuit.

What is the unit of electric current?

• Volt (V)

• Ohm (Ω)

• Ampere (A)

• Watt (W)

What types of charges attract?

• Positive and Negative charges attract each other.

• Positive and Positive charges attract each other.

• Negative and Negative charges attract each other.

• Neutral and Positive charges attract each other.

What is a conductor?

• A material that allows electric charges to flow easily, such as copper.

• A material that prevents electric charges from flowing.

• A type of electrical device that stores energy.

• A material that only conducts heat, not electricity.

What kind of charge is this? (Example: An object with more electrons than protons)

• Positive charge

• Negative charge

• Neutral charge

• Electromagnetic charge

What is an insulator?

• A material that allows electric charges to flow easily, such as copper.

• A material that does not allow electric charges to flow easily, such as rubber.

• A material that can conduct electricity under certain conditions, such as silicon.

• A material that absorbs electric charges, such as wood.

What happens when two objects with the same charge come close?

• They attract each other.

• They repel each other.

• They have no effect on each other.

• They explode.

What is Ohm's Law?

• Ohm's Law states that the current (I) is inversely proportional to the voltage (V) across two points.

• Ohm's Law states that the current (I) through a conductor is directly proportional to the voltage (V) and inversely proportional to the resistance (R).

• Ohm's Law states that the voltage (V) is equal to the resistance (R) multiplied by the current (I).

• Ohm's Law states that the resistance (R) is equal to the current (I) divided by the voltage (V).

What is static electricity?

• Static electricity is the buildup of electric charge on the surface of objects.

• Static electricity is the flow of electric current through a conductor.

• Static electricity is the energy produced by moving electrons in a circuit.

• Static electricity is the discharge of electricity through the air.

What is an electric circuit?

• An electric circuit is a closed loop that allows electric current to flow.

• An electric circuit is a device that stores electrical energy.

• An electric circuit is a type of electrical appliance.

• An electric circuit is a pathway for sound waves to travel.
