Answer:
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.
