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.
What is the resistance formula?
The formula to calculate the resistance using Ohm's Law is given as follows: R = V I. where, R is the resistance of the resistor R in ohms (Ω) V is the voltage drop in the resistor in volts.
What is the current drawn by a 1200 watt hair dryer connected to 120 V outlet?
from the expression watts = amperes X volts, we see that the current = 1200 W/120 V = 10 A, so the hair dryer will operate when connected to the circuit.
How hot does a 2000 watt hair dryer get?

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).
Will a 1200 watt hair dryer operate on a 120 volt line if the current is limited to 15 amperes by a safety fuse can two hairdryers operate on this line?
if a 120-V line to a socket is limited to 15 A by a safety fuse, will it operate a 1200-W hair dryer? Yes. from the expression watts = amperes X volts, we see that the current = 1200 W/120 V = 10 A, so the hair dryer will operate when connected to the circuit.
Is a 1200 watt hair dryer good?
Generally, a 1000W-1200W hair dryer works well for those with short-to-medium hair, whereas a stronger hair dryer with a rating of 1500W-1800W is better suited for those with long, thick hair.
How many watts is a strong hair dryer?
Hair dryers typically use 1,875 watts (1.875 kWh) on the highest power setting, 975 watts (. 975 kWh) on medium and 862.5 watts (. 8625 kWh) on low.
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 calculate resistance in watts?
If we assume a resistor with a fixed resistive value of 100 Ohms, passes a current of 0.5 amperes (500mA), then the power dissipated by it will be, from Ohm's Law, P = I2R = 25 watts, which is equivalent to 25 joules of work per second.
How do you find resistance from Watts?
- I = V / R.
- I = P / V.
- I = √(P / R)

How much power is used by a calculator that operates on 8 V and 0.1 A?
0.8 W How much power is used by a calculator that operates on 8 volts and 0.1 ampere? If it is used for one hour, how much energy does it use? Answer: Power = current × voltage = (0.1 A) × (8 V) = 0.8 W.
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.
