∙ 14y agoThe resistance of a circuit if current flow is 6 amperes and voltage drop is 120 volts is 20 ohms. (Ohm's law: resistance is voltage divided by current.)

What is the resistance of a circuit with 120V and 10A?
Assuming DC and resistive loads, resistance equals voltage across the load, divided by the current through it. In this case 120/10 or 12 ohms.
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
How much voltage does a line with resistance of 10 ohms and a current of 20 amps?
V = i*r v = 2 * 60 v= 120v
What is the resistance of a lightbulb using Ohm's law?
By Ohm's law, resistance is voltage divided by current, so the resistance of a light bulb can be measured by observing the voltage across it simultaneously with observing the current through it. Interestingly, the hot resistance is significantly different that the cold resistance, so measuring resistance with an ohmmeter will not give a meaningful resistance. This is because the resistance of a light bulb has a positive temperature coefficient. Take a typical 60 W 120V light bulb, for instance... Its cold resistance is about 16 Ohms. Calculate current and power at 120 V and you get 7.5 A and 900 W. The truth is that at 60 W, the bulb pulls 0.5 A and has a resistance of 240 Ohms.
A 120-volt household circuit delivers 350 watts of power to an appliance and another 10 watts of power are consumed by the circuit With no ground fault. How much current is carried by the neutral?
Here is my full question - A typical 120-volt household circuit delivers 350 watts of power to an appliance, and another 10 watts of power are consumed by the circuit. There is no ground fault. a. How much current is carried by the hot wire? b. How much current is carried by the neutral? c. How much current is carried by the grounding conductor? d. Calculate the resistance of the circuit: by "consumed by the circuit" I assume you mean consumed by the wires. Assuming resistive loads only, the total load is 360 watts, thus the current is 3 amps. The current flows in the hot and the neutral.

An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
What is the resistance of a 120 volt 15 amp circuit?
A circuit breaker is designed to "trip" when more than its rated current passes through the breaker. The current is caused by the 120V across a load of a certain resistance. The wire conducting the current must be sized to the current. For 15 amps you need 14 gauge wire. The breaker will be labeled and will have a current and voltage rating printed on the breaker.
What is the resistance of a circuit with 120V and 1A?
You are mad idiots fools
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
A kettle is connected to a 120v outlet with a resistance of 9.6 ohms what is the current required to operate the kettle?
The formula you are looking for is V = IR where V = Voltage I = Current R = Resistance With some formula manipulation and numbers plugged in you get I = 120V / 9.6Ω I = 12.5A The kettle would have 12.5 volts of current running through it.
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
How do you upgrade from 120V 15A to 120V 20A or from 240V 20A to 240V 30A?
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.
How many amps are in a 110 circuit?
The circuit will have zero amps. There is one value missing from the question. The equation that you are looking for is I = E/R. Amps = Volts/Resistance or I = W/E or I = Sq Root of W/R.Once you find the resistance or watts, using the equations above you can find the amperage the circuit draws.
What ohm value or what combenation of resistors are needed to draw 20amps at 120v?
ohms = volts/amperes 6 ohms = 120 volts / 20 amperes
