How many units of electrical energy would a 2000 W electrical appliance, used for 2 hours everyday consume in the month of April?

Options

A. 120
B. 30
C. 100
D. 10

Explanation

To find out how many units of electrical energy a 2000 W electrical appliance would consume in the month of April when used for 2 hours every day, we can follow these steps:

### Step 1: Determine the total number of days in April
April has 30 days.

### Step 2: Calculate the total hours the appliance is used in April
The appliance is used for 2 hours each day. Therefore, the total time (T) the appliance is used in April is:
\[ T = \text{Number of days} \times \text{Hours per day} = 30 \, \text{days} \times 2 \, \text{hours/day} = 60 \, \text{hours} \]

### Step 3: Calculate the total energy consumed by the appliance
The energy consumed (in watt-hours) can be calculated using the formula:
\[ \text{Energy (in watt-hours)} = \text{Power (in watts)} \times \text{Time (in hours)} \]
Substituting the values:
\[ \text{Energy} = 2000 \, \text{W} \times 60 \, \text{hours} = 120000 \, \text{Wh} \]

### Step 4: Convert watt-hours to kilowatt-hours
Since 1 kilowatt (kW) = 1000 watts (W), we convert watt-hours to kilowatt-hours (kWh):
\[ \text{Energy (in kWh)} = \frac{120000 \, \text{Wh}}{1000} = 120 \, \text{kWh} \]

### Conclusion
The total electrical energy consumed by the 2000 W appliance used for 2 hours every day in April is **120 kWh**.
