To calculate the cost of running a TV for 8 hours, you need to know the TV's wattage and your electricity rate per kWh. For example, a 100-watt TV running for 8 hours uses 0.8 kWh (100 watts * 8 hours / 1000). If your electricity rate is $0.15 per kWh, it will cost 0.8 kWh * $0.15 = $0.12 to run the TV for 8 hours.**
