Q1. How do you calculate the cost and consumption of electricity?
Ans. 
Calculating electricity cost involves understanding consumption, rates, and usage patterns.
• Identify the wattage of the appliance (e.g., a 100W bulb).

• Calculate daily usage in hours (e.g., 5 hours/day).

• Use the formula: Energy (kWh) = Power (kW) × Time (h).

• For the bulb: 0.1 kW × 5 h = 0.5 kWh per day.

• Multiply by the cost per kWh (e.g., $0.12/kWh): 0.5 kWh × $0.12 = $0.06/day.
