A hair dryer draws 1 200 W, a curling iron draws 800 W, and an electric light fixture draws 500 W. If all three of these appliances are operating in parallel on a 120-V circuit, what is the total current drawn?

Therefore,

The Total current drawn is 20.83 Ampere.

Explanation:

Given:

Voltage, V = 120 V

Power of Appliances,

P1 = 1200-W Hair dryer,

P2 = 800-W Curling iron,

P3 = 500-W Light

To Find:

Current  flowing in the line, I = ?

Solution:

We have Power formula,

Current for hair dryer,

Substituting the values we get

Similarly for curling iron,

Similarly for electric light

As all three of these appliances are operating in parallel on a 120-V circuit,  the total current will be given as

Substituting the values we get

Therefore,

The Total current drawn is 20.83 Ampere.
