Calculation of Electrical Energy Consumed by the Bulb
Calculation of Cost of Electrical Energy Consumed by the Bulb
Explanation
The given electric bulb has a power rating of 100 W and a voltage rating of 200 V. However, it is connected to a 220 V source. The time for which the bulb is used is 2 hours per day for 10 days. Therefore, the total time for which the bulb is used is 20 hours.
Using the formula for electrical energy, we can calculate the energy consumed by the bulb. The energy consumed by the bulb is 2000 Wh or 2 kWh.
To calculate the cost of electrical energy consumed by the bulb, we need to know the cost of 1 unit of electrical energy. In this case, it is given that 1 unit of electrical energy costs Rs 2. Therefore, the cost of 2 kWh of electrical energy consumed by the bulb is Rs 4.
- Given, power (P) = 100 W
- Voltage (V) = 200 V
- Time (t) = 2 hours/day x 10 days = 20 hours
- Using the formula, Energy (E) = P × t
- E = 100 W × 20 hours = 2000 Wh
- Converting Wh to kWh, E = 2000/1000 = 2 kWh
Calculation of Cost of Electrical Energy Consumed by the Bulb
- Given, cost of 1 unit of electrical energy = Rs 2
- 1 unit of electrical energy = 1 kWh
- Cost of 2 kWh = 2 x Rs 2 = Rs 4

The given electric bulb has a power rating of 100 W and a voltage rating of 200 V. However, it is connected to a 220 V source. The time for which the bulb is used is 2 hours per day for 10 days. Therefore, the total time for which the bulb is used is 20 hours.
Using the formula for electrical energy, we can calculate the energy consumed by the bulb. The energy consumed by the bulb is 2000 Wh or 2 kWh.
To calculate the cost of electrical energy consumed by the bulb, we need to know the cost of 1 unit of electrical energy. In this case, it is given that 1 unit of electrical energy costs Rs 2. Therefore, the cost of 2 kWh of electrical energy consumed by the bulb is Rs 4.
