The total load in watts would be W = A x V. 20 x 120 = 2400 watts. Any wattage higher than this will trip the breaker and shut the circuit off.

The theoretical resistive load is V/I = 120/20 = 6 Ohms. The lower the resistance the higher the current. Usually you don't want to operate above the 80% point so the number would be 120/16 = 7.5 Ohms.
What else can I help you with?
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Can you use a 6 volt relay to 230 volt circuit?
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
What voltage is applied to a 4 ohm resistor of the current is 1.5 amps?
It all depends on the load. The formula for calculating amps, volts or ohms (resistance of load) is E=IR, where E is the voltage, I is the current and R is the load or circuit resistance. So, if you know the resistance in ohms and the current in amps, you multiply them together to get the voltage of the circuit. Again, it depends on the load, so a 12 volt car battery can deliver 1.5 amps if the load is 8 ohms whereas a 120 volt circuit will deliver 1.5 amps if the load is 80 ohms. This is all simplified and is based on a resistive load. If the load is capacitive or inductive, then phase angles come into play and the math is more complicated using imaginary numbers and J-operators.
A digital circuit can be corrupted by electrical noise having a value of?
1 volt
How do you test the power in a circuit?
A volt meter will do the job.
What does Volt-Amp mean?
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.
How long does current remain in a 220 volt circuit?
The current in a 220 volt circuit depends on the resistance of the load connected to it. Ohm's Law (I = V/R) states that current (I) is equal to voltage (V) divided by resistance (R). So, the current will vary based on the resistance of the circuit.
What is the appropriate wire size for a 220 volt circuit with a 40 amp load?
For a 220 volt circuit with a 40 amp load, the appropriate wire size would be 8 AWG (American Wire Gauge) copper wire.
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
How do you connect a volt to a circuit?
A volt can not be connected to a circuit.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What are the properties of a circuit?
When you mean simple circuit, I assume a source of one volt across a load of one ohm, which, according to Ohm's Law, equals one amp.
What is the total resistance of a parallel circuit with branch voltages of 440 volt and 440 volt and branch currents of 4 amp and 16 amp?
resistance = volt / current . 440 volt across a parallel circuit means the same 440 volt across both resistance s. hence resistance r = volt / current . 440 / 20 amp = 27.5 ohms total resistance
Placing a voltmeter into a circuit will raise the circuit resistance?
Placing a voltmeter into a circuit will not raise the circuit resistance. A voltmeter is designed to have a very high resistance so that it does not significantly affect the circuit being measured. The resistance of the voltmeter is much higher than the resistance of the circuit, so it has minimal impact on the overall resistance of the circuit.
If R1 equals 2 and R2 equals 4 in a 12 volt series circuit what is the total circuit resistance?
