A 120-V electrical line in a home is connected to a 100-W lightbulb, a 180-W television set, a 230-W desktop computer, a 1050-W toaster, and a 240-W refrigerator.

How much current is flowing in the line?

Express your answer with the appropriate units.

Therefore,

15 Ampere current is flowing in the line.

Explanation:

Given:

Voltage, V = 120 V

Power of Appliances,

P1 = 100-W lightbulb,

P2 = 180-W television set,

P3 = 230-W desktop computer,

P4 =  1050-W toaster, and

P5 = 240-W refrigerator.

To Find:

Current  flowing in the line, I = ?

Solution:

We have Power formula,

For Household Voltage Remain Same and Current will differ and there will be a Parallel Connection for the Appliances,

Therefore,

1 .For lightbulb,

Substituting the values we get

2. Similarly for television,

Substituting the values we get

3. Similarly for desktop computer,

Substituting the values we get

4. Similarly for toaster,

Substituting the values we get

5. Similarly for refrigerator,

Substituting the values we get

In Parallel connection Total current 'I' is given as,

Substituting the values we get

Therefore,

15 Ampere current is flowing in the line.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
