Atypical electric hair dryer designed to operate on a 120-v ac household circuit is rated at a power consumption of 1500 watts. for calculating effective average values, we can treat 120-v ac as a dc current. a. what average current flows through the dryer? b. what is the resistance of the dryer?

(a). The average current flows through the dryer is 12.5 A

(b). The resistance of the dryer is 9.6 Ω

Explanation:

Given that,

Voltage = 120 V

Power = 1500 W

(a). We need to calculate the average current flows through the dryer

Using formula of current

Where, P = power

V = voltage

Put the value into the formula

(b). We need to calculate the resistance of the dryer

Using Ohm's law

Where, I = current

Put the value into the formula

Hence, (a). The average current flows through the dryer is 12.5 A

(b). The resistance of the dryer is 9.6 Ω

the answer for apex is the lowest
