This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

• 3 Amps

• 192 Amps

• 2 Amps

• 4 Amps

Why are electrical cords covered in plastic or rubber?

• because plastic and rubber are insulators which keeps us safe

• because it looks nicer

• because plastic and wire help conduct electricity

• because wires are color coded based on voltage
