🔍 Key Concepts

• Difference between voltage, current, resistance, and power in a basic DC circuit • The standard SI (International System of Units) names for electrical quantities • Relationship: Power = Voltage × Current

💭 Think About

• Which quantity describes how much energy per unit time is being used or produced in a circuit? • Which unit is used when you talk about the power rating of light bulbs or engines (e.g., a 60-___ light bulb)? • For each choice, ask: does this unit measure push (potential), flow (current), opposition to flow (resistance), or rate of doing work (power)?

✅ Before You Answer

• Match each unit: ohm = resistance, volt = electrical potential, ampere = current, and identify which remaining unit is for power • Think of household appliances: what unit is printed next to their power rating label? • Verify which unit appears in the common electrical power formula P = V × I as the result of the calculation
