Question

Name at least two independent variables that

could result in a change in a monthly electric bill.

Answer 1

Two independent variables that could result in a change in a monthly electric bill are the number of electric appliances used and the duration for which they are left on.

Step-by-step explanation:

Two independent variables that could result in a change in a monthly electric bill are the number of electric appliances used and the duration for which they are left on.

The more electric appliances a household uses and the longer they are left on, the higher the electric bill. This is because the relationship between energy and power (P = E/t) shows that the energy used (E) is directly proportional to the power (P) and the time (t) for which the appliances are left on.

For example, if a household increases the number of appliances used or the duration for which they are left on, the energy usage and ultimately the monthly electric bill will increase.

Answer 2

Outside temperature and humidity and How often the electrical appliances inside the house are used.

Step-by-step explanation:

Hope this helps. Also anything that changes can effect the monthly electricty bill.
