W2 Electricity

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light
