E = I R = 22 x 7 = 154 volts.
Power (Watts) = Current (Amps) * VoltagePower = 22Amps * 240 VoltsPower = 5,280 Watts5280
V=I*R Where: V is voltage I is the current in ampers R is resistance in ohms. So, if the current is 15 A and the resistance is 5 ohms, then the voltage must be 15 A *5 ohms = 75 V.
No, it opens the circuit so that no current flows.
There are a couple ways to vent a dryer, my personal favorite is the dryer vent vacuum. They also have dryer vent hoods, and kits available for installation that will increase the effectiveness of your dryer.
The net effective resistance of 5 ohms, 10 ohms, and 20 ohms in series is 35 ohms.The current through the net effective resistance is [ I = E/R ] = 120/35 = 3.429 Amp. (rounded)Note: If you try this at home, be aware that these resistors will dissipatethe 5 ohm . . . 58.8 wattsthe 10 ohm . . . 117.6 wattsthe 20 ohm . . . 235 watts .These are no ordinary resistors, such as hang on the wall in plastic bags at Radio Shack.These would have to be 'power' resistors ... like heating coils in a toaster or hair-dryer.
Your hair dryer has a resistance of 220/12 = Ohms. (I'm sure you can do the math.)
We know that Voltage = Current x Resistance, so if E = I x R, then E = 20 x 12 = 240 volts, and the dryer must be plugged into a 240 volt outlet.
Ohm's Law can be applied to a hair dryer to determine the relationship between the voltage supply, current flowing through the device, and its resistance. By knowing the voltage of the power source and the resistance of the hair dryer (typically indicated on the device), you can calculate the current flowing through the hair dryer using the formula I = V/R, where I is the current, V is the voltage, and R is the resistance.
The current flowing through the hair dryer would be 4.8 amps (120 V / 25 Ω = 4.8 A).
Power (Watts) = Current (Amps) * VoltagePower = 22Amps * 240 VoltsPower = 5,280 Watts5280
The resistance of the hair dryer can be calculated using Ohm's Law, which states resistance (R) equals voltage (V) squared divided by power (P). Plugging in the values, the resistance of the hair dryer is approximately 13.09 ohms.
The formula you are looking for is E = I x R.
4800 watts because watts = volts x amps.
A clothes dryer typically draws the most amps among common home appliances, with an average of around 20 amps.
Heat energy is produced in a hair dryer by passing an electric current through a coil of wire called a heating element, which generates heat through resistance. Sound energy is produced by the motor fan inside the hair dryer as it spins rapidly to create airflow.
A hair dryer is powered by alternating current (AC) electricity. This type of current allows the hair dryer to function effectively by converting electrical energy into heat and air flow.
A typical hair dryer draws around 10-15 amps when operating at its highest setting. It is important to check the specific amperage rating of the hair dryer you are using to ensure it is compatible with the electrical circuit you are using.
