The electrical energy consumed per day:
• Given that an electric bulb of 100 watts is used for 3 days
• Electrical energy is the power consumed by the appliances in one hour
• Electrical energy = Power × Time
• Energy is given in kilowatt per hour or watt per sec or watt per hour
• Energy per day = 100 watt × 24 hr
= 2400 watt hr
