Question

According to PSE&G, the average New Jersey home uses 8386 kWh of electricity in one year. How many joules does that make?

Answer 1

To determine the energy usage in joules for an average New Jersey home, multiply the annual electricity usage in kWh (8386) by the joules per kWh conversion (3.6 × 10^6), resulting in approximately 30.19 × 10^9 joules.

Step-by-step explanation:

To calculate the energy consumption in joules for the average New Jersey home that uses 8386 kWh of electricity in one year, we first need to know the conversion factor between kilowatt-hours and joules. According to the given information, 1 kWh is equivalent to 3.6 × 106 joules. Therefore, we can find the total energy consumption in joules by multiplying the annual kWh usage by this conversion factor.

The calculation follows as:

1. × Multiply the average annual kWh usage (8386 kWh) by the conversion factor (3.6 × 106 joules per kWh).
2. The energy consumption in joules equals 8386 × 3.6 × 106 joules.
3. After performing the multiplication, we get 30,189,600,000 joules or 30.19 × 109 joules.

In conclusion, the average New Jersey home uses approximately 30.19 × 109 joules of electricity in one year.

Answer 2

`3.01* 10^(10)\ J`

Step-by-step explanation:

It is given that,

The average New Jersey home uses 8386 kWh of electricity in one year.

We need to find the electricity that make in one year.

We know that,

`1\ kWh=3.6* 10^6\ J`

or

`8386\ kWh=8386 * 3.6* 10^6\ J\\\\=3.01* 10^(10)\ J`

So, it will make
`3.01* 10^(10)\ J` or energy in one year.
