What is the resistance of a hair dryer?
What is the resistance of the hair dryer? R = (Voltage)/(Current)= 120 V/13 A = 9.2 W. If two resistances are linked together with a single wire as in the diagram, the current through each resistor is the same. The potential drop across each resistor is equal to the current times the resistance of that resistor.

How do you find resistance with voltage and watts?
Ohms Law and Power
- To find the Voltage, ( V ) ( V = I x R ) V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) ( I = V ÷ R ) I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) ( R = V ÷ I ) R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) ( P = V x I ) P (watts) = V (volts) x I (amps)
How do you calculate voltage resistance?
From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).
How many amps does a 1500 watt hair dryer pull?
12.5 amps Using the W ÷ V = A variation of Ohm's law, you can calculate that 1,500 watts ÷ 120 volts = 12.5 amps. Your hair dryer running a maximum heat can draw 12.5 amps of power.
How many amps does a 2000w hair dryer use?

| Iron | 1200 | 10 |
| Microwave oven | 1500 | 13 |
How many amps does a 120 volt dryer use?
110V / 120V dryers typically use between 7.5 amps and 15 amps. What is this? These 110V / 120V dryers are commonly referred to as compact or portable dryers. These dryers are usually designed for use in smaller spaces, like apartments, and to run off of standard 110V / 120V household circuits.
Are 12 volt hair dryers any good?
WARNING: A 12v hair dryer will never be anything like your home hair dryer. It will be worse than the worst household hair dryer you've ever tried. It will be much weaker, and much slower. But you're camping – so we arent in a hurry to do anything usually!
What watt hair dryer do hairdressers use?
1800-1875 watts "Although some professional hair dryers even go up to 3600 watts, I would recommend a hair dryer of 1800-1875 watts for the consumer to use," says Jennifer Buchalla, celebrity hairstylist and makeup artist.
How do you convert watts to resistance?
This converter will calculate any two of the four electrical values (ohms, volts, watts, or amps) from the other two. Plus, each result includes the Ohm's Law formula used and the steps to solving it….Find Watts from Amps and Ohms:
| Watts | = | Amps2 * Ohms |
|---|---|---|
| Watts | = | 144 * 3 |
| Watts | = | 432 |
How do I calculate resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
How do you find resistance from Watts?
- I = V / R.
- I = P / V.
- I = √(P / R)

How many watts is a hair dryer?
Most hair dryers will have a power rating label to indicate the maximum wattage, which typically ranges from 800 to 1800 watts.
