Magic of Electrons Unit 2

What is electric current?

• The flow of water in a conductor.

• The flow of electric charge in a conductor.

• The flow of heat in a conductor.

• The flow of sound in a conductor.

What is voltage?

• The pressure that pushes electrons

• The resistance to the flow of electric current.

• The flow of electric current in a circuit.

• The amount of electric charge in a circuit.

Using Ohm's Law, what is resistance?

• V x R

• I / V

• V / I

• I x R

State Ohm's law.

• V = IR

• V = I/R

• R = IV

• V=AR

What is a series circuit?

• A series circuit is a circuit in which the components are connected in a random order, so the current flows through each component unpredictably.

• A series circuit is a circuit in which the components are not connected to each other, so the current does not flow.

• A series circuit is a circuit in which the components are connected in a single loop, so the current flows through each component in sequence.

• A series circuit is a circuit in which the components are connected in parallel, so the current flows through each component simultaneously.

What happens to the current in a series circuit if one resistor is removed?

• The current increases.

• The current becomes zero.

• The current remains the same.

• The current decreases.

What happens to the voltage in a series circuit if one resistor is removed?
