Multiple Choice

A Punnet Square will 

• tell you exactly what your offspring will look like

• increase the chance you pass on recessive traits

Multiple Choice

The force that pushes the electricity through a circuit is called...

• resistance

• voltage

• current

• switch

Multiple Choice

The flow of electricity through a conductor is called...

• resistance

• voltage

• current

• source of electric current

Multiple Choice

Current times Resistance (I X R) equals

• Power

• Voltage

• Amperage

• Ohm

Visualizing Current

• The negative terminal of a battery has tons of electrons.

• When forced, they leave, complete the circuit, and return to the positive terminal.

• Resistors slow them down.

V = Voltage / I = Current / R = Resistance

Multiple Choice

The plastic covering is there to:

• Provide a conductor for electrical energy to flow.

• Provide an insulator so that electrical energy will not pass outside of the wires.

• Provide a conductor so that electrical energy can NOT flow.

• Provide an insulator so that electrical energy can flow.

Multiple Choice

Electricity that flows in a closed path is called a

• battery

• current

• circuit

• resistor

Multiple Choice

What is Resistance?

• The flow of electrons

• Electric potential difference

• A power source

• The ability to reduce the flow of electrons

Multiple Choice

The mathematical relationship among Voltage, Current, and Resistance

• Faraday's Law

• Tesla's Law

• Edison's Law

• Ohm's Law

Multiple Choice

Voltage divided by Resistance (V / R) equals

• Current

• Power

• Ohms

• Watts

Multiple Choice

What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V

• 10 V

• 2.5 V

• 0.4 V

• All electronic circuits have a path for electrons to flow and an energy source.

• Electrons will flow from the negative(-) to the positive(+).

• The amount of electron flow will depend on resistance. 

​

Basic Circuits ​

​

Direct Current (DC) electrons flow in only one direction.

​

Examples:  a battery, handheld electronics such as an iPod, and other devices like an automobile​

​

Direct Current

• Alternating Current (AC) electrons flow back and forth, negative (-) to positive (+) to negative (-)

  • Examples: the electrical appliances at your house 

​

​Some text here about the topic of discussion.

Alternating Current

• An insulator is any material that prevents the flow of electrons.

  • Insulators typically have five to eight free electrons in the outer ring, which means they are tightly held to the atom and cannot easily move.

• Insulator material includes glass, rubber, and plastic.

Insuators

• A conductor is any material that easily allows electrons to flow.

  • Conductors typically have one to three free electrons in the outer ring, which means they are loosely held to the atom and can easily move.

• Conductor material includes copper and gold.

​

Conductors

• A semiconductor is neither a good conductor or insulator.

  • Semiconductors have exactly four free electrons in the outer orbit and are commonly used to manufacture diodes, transistors, and integrated circuit chips. 

• Semiconductor material includes carbon, silicon, and germanium.

Multiple Choice

What is a voltage

• Voltage is the electrical force that moves electrons through a conductor.

• Voltage is the electrical force that moves protons through a conductor.

Multiple Choice

What is current ?

• Current is the quantity or flow rate of protons moving past a point. 

• Current is the quantity or flow rate of neutrons moving past a point. 

• Current is the quantity or flow rate of electrons moving past a point. 

• Current is the quantity or flow rate of DNA moving past a point.
