How do you find resistance with voltage and watts?
For example if the power is 100 watts and the voltage is 50 volts, the current is 100 / 50, or 2 amps. Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current.
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 watts is a professional hair dryer?

What is the voltage of a hair dryer?
120-volt hair dryers usually use between 15 and 20 amps, and connect to a 120-volt outlet.
Is 1000 watts enough for hair dryer?
Yes, a dryer that has 1000 watts can work for drying thin hair. Many travel-sized dryers are usually 1000 watts. My hair looks frizzy even if I use products and blow-dry.
How do you know if a hair dryer is powerful?
Look for something with a higher wattage. 1800 or higher for thinner hair. Many professional blow dryers have wattage as high as 3600.
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)
