Power in a circuit can be calculated using the formula ( P = V \times I ), where ( P ) is power in watts, ( V ) is voltage in volts, and ( I ) is current in amps. In a 12-volt, 4-amp DC series circuit, the power would be ( P = 12 , \text{V} \times 4 , \text{A} = 48 , \text{W} ). Therefore, the power consumed in this circuit is 48 watts.
What else can I help you with?
If two 2-volt batteries are connected in a series how many volts are available to the circuit?
The formula you are looking for is Vt = V1 + V2.
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 much power is produced by a circuit by a 9 amp 27 volt circuit?
The power produced by the circuit can be calculated using the formula P = I * V, where P is power, I is current, and V is voltage. In this case, P = 9 amps * 27 volts = 243 watts. So, the circuit would produce 243 watts of power.
What is the difference between amps and volt-amps?
Amps (A) measure electrical current flow, while volt-amps (VA) measure apparent power in an electrical circuit, which is the combination of both real power (measured in watts) and reactive power. Essentially, amps refer to current, while volt-amps refer to total power.
If three lamps are connected in series to a 6 volt battery how many volts are impressed across each lamp?
In a parallel circuit, Voltage is constant through out the circuit. Thus, the voltage across each lamp is 6-volts.
If R1 equals 2 and R2 equals 4 in a 12 volt series circuit what is the total circuit resistance?
Series circuit? Add 'em!
What is the difference between volt-amp and watt, and how do they relate to each other in terms of measuring electrical power?
Volt-amp is a unit of apparent power, which is the combination of voltage and current in an electrical circuit. Watt, on the other hand, is a unit of real power, which is the actual power consumed by a device. The relationship between volt-amp and watt is that watt is the product of volt-amp and power factor, which represents the efficiency of the electrical system. In simple terms, watt is the actual power used by a device, while volt-amp is the total power flowing through the circuit.
How do you test the power in a circuit?
A volt meter will do the job.
How do you get 24 volt power from a 12 volt battery?
use two 12 volt batteries in series.
What does 20VA mean?
20VA stands for 20 volt-amperes, which is a unit used to measure apparent power in an electrical circuit. It is calculated by multiplying the voltage by the current in an AC circuit. It represents the total power in the circuit, including both real power (watts) and reactive power (volt-amps reactive).
How do you connect a volt to a circuit?
A volt can not be connected to a circuit.
What is the difference between watts and volt-amps?
Watts measure real power in an electrical circuit, while volt-amps measure apparent power, which includes both real and reactive power. Watts represent actual energy consumed or produced, while volt-amps account for the total power flowing in a circuit.
If two 2-volt batteries are connected in a series how many volts are available to the circuit?
The formula you are looking for is Vt = V1 + V2.
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.
What is the current in a 12-volt circuit with a 6-ohm resistor connected series?
2 A (amperes)
Is it true that volt amps are the same as watts?
No, volt-amps (VA) and watts (W) are not the same. Watts measure real power in an electrical circuit, while volt-amps represent the apparent power, which includes both real power and reactive power.
What is the amps In a simple electric circuit with a 12 volt supply and a 24 ohm resistor?
0.5 amps
