Question

according to the values provided in the video, how many hair dryers running simultaneously would it take to reach the total current available coming into your house?

Answer 1

Even one hair dryer running at full capacity, which is about 1,800 W, will reach the maximum continuous power limit of a typical 15-Ampere, 120-Volt household circuit, which is 1,440 W due to the 80% safety limit factor. Therefore, you cannot run more than one hair dryer at full capacity without overloading the circuit.

Step-by-step explanation:

To determine how many hair dryers running simultaneously it would take to reach the total current available coming into your house, we need to consider the power consumption of a single hair dryer and the total power supply of the household.

Let's assume a hair dryer consumes around 1,800 W of power when running at full capacity. Household circuits are typically limited to 80% of breaker current capacity for continuous use, as safety regulations suggest. If a household outlet is on a 15-Ampere, 120-Volt circuit, the maximum continuous power that can be used without exceeding the safety limit is:

Power = 0.8 (safety limit factor) x Current x Voltage
Power = 0.8 x 15 A x 120 V
Power = 1,440 W

Therefore, the number of hair dryers running at full capacity that would match the power availability of the household circuit would be:

Number of hair dryers = Total power available / Power per hair dryer
Number of hair dryers = 1,440 W / 1,800 W

However, this calculation shows that even one hair dryer is enough to reach the maximum continuous power limit allowed by safety regulations on a single 15-A, 120-V household circuit. So, a single hair dryer running at full capacity is all the circuit can handle continuously without overloading.

Answer 2

Given the electrical specifications, a standard 15-Ampere, 120-Volt household circuit can continuously support a maximum of 1440 Watts. Since a hair dryer consumes about 1800 Watts at full power, the circuit could not support even one hair dryer without overloading.

Step-by-step explanation:

To answer the question of how many hair dryers running simultaneously it would take to reach the total current available coming into a house, we need to consider the electrical specifications provided in the videos and the statements. Safety regulations suggest that the typical household circuit can continuously support approximately 80% of the breaker current capacity. For a standard 15-Ampere, 120-Volt household circuit, this capacity would be:
80% of 15 A = 12 A (continuous current capacity)

Using the power formula P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts, let's determine the maximum continuous power supported by this circuit:
P = I * V
P = 12 A * 120 V = 1440 W

Given that a typical hair dryer consumes about 1800 W when running at full power, to find out how many hair dryers can be supported, you divide the total circuit power capacity by the power consumption of the hair dryer:
1440 W / 1800 W = 0.8 hair dryers

Since you cannot have a fraction of a hair dryer, it's clear that even one hair dryer running at full blast would exceed this circuit's continuous capacity. However, it's important to note that hair dryers can operate at lower settings which would draw less current and allow for more than one to be used on the same circuit. Nonetheless, for the question, if all hair dryers were to run at full power, the circuit could not even support one without overloading.
