Power is voltage times amperes, so 28 volts and 4 amperes is 112 watts.
The reason for this is that voltage is actually joules per coulomb, and amperes is actually coulombs per second. Multiplying them together produces joules per second, which is the definition of watts.
P = I x V P = 22 x 220 Therefore Power consumed = 4840 Watts Or 4.84kW
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.
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
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.
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.
Amps (amperes) measure current flow in a circuit, showing how much electricity is flowing. Watts measure power, representing the rate at which energy is consumed or produced. In simple terms, amps indicate the amount of electricity flowing, while watts indicate how much work or energy is being used.
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.
A 120 v circuit would supply 120 v to both resistors if they are in parallel, which is 120/100 amps into a 100 ohm load, and 120/80 amps into am 80 ohms load, which totals up to 2.7 amps, so the total power is 120x2.7 watts or 324 watts.
125 amps is a measure of electrical current, indicating the flow of electric charge in a circuit. It represents the amount of current that can flow through a conductor, such as a wire, when a voltage is applied. In practical terms, 125 amps can power multiple electrical devices or appliances, depending on their individual power requirements. To understand its significance, it's essential to consider the voltage and the total power (in watts) being consumed in the system.
Power = E times I = (24 x 2) = 48 watts
Oh, honey, 500VA is equal to 500 watts. VA stands for volt-amps, which is the apparent power in an electrical circuit, while watts are the real power. So, in this case, they're one and the same. Hope that lights up your day!
The power used by the circuit can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. In this case, P = 120 V x 6 A = 720 watts. Therefore, the circuit is using 720 watts of power.
