🔍 Key Concepts
• Ohm’s Law basics: how voltage, current, resistance, and power relate
• Difference between electrical current, voltage, capacitance, and power
• Common unit used to rate the power output of motors, lights, and generators
💭 Think About
• Ask yourself: which of these units is used when you talk about how much work per second an electrical device can do?
• Which unit appears on light bulbs and generators when showing how much power they consume or produce?
• Which of these units is associated with current, which with voltage, which with capacitance, and which with power?
✅ Before You Answer
• Match power with the correct physical concept: rate of doing work or energy per unit time
• Mentally pair: ampere = current, volt = voltage, farad = capacitance and see what’s left for power
• Think of typical ratings like "100 ___" on a light bulb and identify what unit normally fills that blank
