A 120 volt appliance requires 15 amps to operate - what is the resistance of the appliance?

For calculation purposes R = E/I. R = 120/15. R = 8 ohms. This is hypothetical because of the internal components that make up most appliances.

Can you use32amp circuit for a 15amp appliance?
If it is a 32-amp circuit you can use any appliance that takes less than 32 amps. That includes a 15-amp appliance. All appliances fed from that circuit must use 32 amps or less in total.
Why is it dangerous to pass to much current through the mains cable?
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
What is the resistance of the circuit if the voltage is 230 volts and the current flowing is 5 amps?
The resistance of the circuit will be 46 ohms
What size wire do you need for 15 amps?
AWG 10.
How much power is consumed by a 6 ohm load with 12 volts applied?
Volts = Amps x Resistance Therefore Amps = Volts / Resistance
What is the voltage of an appliance that has a current of 3 amps and a resistance of 4 ohms?
12 volts.
What is a resistance of the appliance If 24 amps of current flows through an appliance connected to a 120 v circuit.?
Let R be the resistance, V the voltage, and I the current R = V / I R = 120 / 24 R = 5 ohm
An electric appliance draws 1.5 amperes of current when it is connected to a 24-volt source - What is the resistance of this appliance?
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
Why does a slow motor create high amps?
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
How many volts would does it take to operate a DVD player with 550 ohms resistance and a current of 0.2 amps?
In the U.S. 120 volts. <<>> Using the equation E = I x R, Volts = Amps x Resistance = 110 volts.
Will a 34 amp appliance work on 20 amps?
No.
How many amps in 120volts and 500ohms?
You use Ohm's Law to make your calculation. Volts = Amps x Resistance Amps = Volts / Resistance
What are the limitations of ohms law?
It requires the ability to multiply and divide. It requires the ability to mentally separate voltage from current and to understand resistance and when to add resistance for series circuits and worse identify and calculate parallel loads.
What effect are there when resistance is increased in the size of the current?
Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms
What happens if you plug a 220 volt appliance into a 230 volt outlet?
Nothing drastic happens, the appliance will operate as normal. The voltages 220 to 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/230V = 10.4 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.
A 60 Watt appliance is plugged into a 120 Volt AC outlet How much current is the appliance drawing when it is turned on?
Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.
How many amps does a circuit with 110 volts and a resistance of 7ohms have?
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
