Electricity Basics

Match: ⚡ = ? | 🔦 = ? | 🔋 = ?

• Voltage

• Bulb

• Battery

• Current

How is voltage the 'peer pressure' of circuits?

• Electrical 'push' that makes current flow!

• Resistance that opposes current flow.

• The amount of energy stored in a circuit.

• The speed at which electrons move through a conductor.

Why is current like students rushing through a hallway?

• Flow rate of charge (electrons!), measured in amps (A)!

• The speed of light in a vacuum.

• The number of students in a classroom.

• The distance traveled by students in a hallway.

Where does the ammeter go? (Hint: __ series!)

• In parallel

• Always in series!

• At the end of the circuit

• Nowhere in the circuit

Why is a voltmeter the 'nosy neighbor' of circuits?

• Measures current in series.

• Measures resistance in parallel.

• Measures voltage in parallel!

• Measures power in series.

Why do wires get hot? (Think collisions!)

• Resistance = electron traffic jams!

• Wires are made of metal which conducts heat.

• Wires are exposed to sunlight.

• Wires are too long and create friction.

V=IR is like which TikTok trend?

• Pressure (V) ÷ Resistance (Ω) = Flow (I)!

• Dance Challenge: Move with the Flow!

• Cooking Hacks: Heat and Resistance!

• Fashion Trends: Layering for Resistance!

How is a resistor like a bouncer?

• Controls electron flow → heat!

• Blocks all electrons from passing through.

• Allows only positive charges to flow.

• Increases the speed of electron flow.

Spot the flaw: ‘Voltmeters measure current.

• True! Voltmeters measure current.

• False! Voltage only.

• Voltmeters measure resistance.

• Voltmeters measure power.

What happens to current if resistance triples?

• Current increases

• Current drops (I=V/R)!

• Current remains the same

• Current fluctuates
