Objective

Create a concept map in Canva that explains Ohm’s Law and the basic concepts of electric circuits.

Instructions

Central Concept

Place “Ohm’s Law and Electric Circuits” at the center.

Main Branches

• Ohm’s Law:

  • Formula: V = I × R
  • Named after Georg Simon Ohm (1827)
  • States that voltage across a conductor is directly proportional to the current through it, if resistance stays constant

• Voltage (V):

  • The electrical push that drives current through a circuit
  • Unit: Volt (V)
  • Source: battery or power supply

• Current (I):

  • The flow of electric charge through a conductor
  • Unit: Ampere (A)
  • Measured with an ammeter

• Resistance (R):

  • Opposes the flow of current
  • Unit: Ohm (Ω)
  • Depends on the material, length, and thickness of the conductor

• Types of Circuits:

  • Series circuit: all components in one loop; current is the same throughout; if one component fails, the whole circuit stops
  • Parallel circuit: components on separate branches; voltage is the same across each branch; if one component fails, others keep working

• Real-Life Applications:

  • House wiring uses parallel circuits
  • Phone chargers use transformers based on Ohm’s Law
  • A light bulb produces light because the filament has high resistance

Design in Canva

• Place the formula V = I × R prominently near the central node.
• Include a triangle diagram (voltage at top, current and resistance at the base) to show how to rearrange the formula.
• Draw a simple series circuit and a simple parallel circuit side by side.
• Color code: blue for voltage, red for current, grey for resistance.

Required Elements

• Formula V = I × R with units for all three quantities.
• Series vs. parallel circuit comparison.
• At least two real-life applications.
• Title: “Ohm’s Law and Electric Circuits.”
