What watt resistor would you need in a 120 volt circuit with a 100 ohm resistor that has 2 amps load already?
If you connect a 100 ohm resistor across 120 volts it will draw 1.2 amps, amps = E/R. Power = volts x amps so the power required for the resistor would be 120 x 1.2 = 144 watts.
It would not matter if the 120 volt circuit already has 2 amps load on it by something else to calculate the wattage of the resistor.
The total power on this circuit would be the 144 watts from the resistor and 240 watts from the other 2 amp load (2a x 120v) for a total of 384 watts.
What else can I help you with?
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
What would happenif you put an 8 amp circuit-breaker in a power circuit?
If you put an 8 amp circuit-breaker in a power circuit that draws more than 8 amps, the circuit-breaker would trip or disconnect the circuit to prevent overheating and potential fire hazards. It is important to always use the correct amperage rating for circuit-breakers to ensure safe operation of electrical circuits.
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
How many amps can a 2.2 megohm resistor handle?
A 2.2 megohm resistor can handle very low current because of its high resistance value. Using Ohm's Law (I = V/R), at a typical voltage of 5V, the current would be around 2.3 microamps.
What is the continuous current draw on a 20 amp circuit breaker?
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.
What is the amps In a simple electric circuit with a 12 volt supply and a 24 ohm resistor?
0.5 amps
Is resistor measured in amps?
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
What will be the amps of a 12v 2amp circuit if there is a 12ohm resistor on it?
The formula you are looking for is I = E/R. Amps = Volts/Resistance. If you say it is normally a 2 Amp circuit, it normally draws 2 amps. Therefore the original resistance offered to the 12v battery is 2/12 = 6 Ohms. If you then connect a 12 Ohm resistor in series, they are added, so R = 18 Ohms. Now if you put 12v across this circuit it will draw 12/18 = 0.66 Amps. Or If you just put a 12 Ohm resistor across the 12v supply it will draw 1 Amp. If the circuit is protected by a 2 Amp fuse, it will not blow, but the resistor will get hot.
Cause of burnout of two resistor?
Too much current flowing in circuit. Sounds like a voltage was applied that exceeded the rating of the resistor. Resistors are rated in watts which is Volts times Amps. As an example, you might have a 1/2 watt rated resistor. If you applied 120 VAC across a 10 Ohm resistance then the current would be 12 Amps. The wattage would be 1,440 watts which is well in access of the rating and would certainly burn out the resistor.
How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
What is the total current flowing through a 45 ohm resistor (1.4 amps) and a 20 ohm resistor (1.8 amps)?
Just add the amps (3.2 amps).
A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source The current running through the circuit is?
E/R=I. 100/50=2 amps.
What voltage does a battery bank that needs 4 A to run?
It would need to be four times higher then the resistance that it is applied against. If the circuit is a 1 ohm resistor, then the voltage would need to be 4 Volts to make 4 amps.
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
How do you use ohm's law to determine the current flowing through a 45 ohm resistor at 1.4 amps?
The current is 1.4 amps, as already stated. The voltage is 45 x 1.4 volts.
How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
