How much power is flowing into your house if the voltage is 120 V and the current is 50 A?
Power is volts times amperes, so 120 V and 50 A would be 6000 watts.
However, it also depends on phase angle and power factor, something that is related to reactive loads such as motors and power supplies. As a result, the power may actually be less, so it is more correct to say 6000 volt-amps. The case of 6000 watts being the same as 6000 volt-amps is only true for a purely resistive load such as a toaster.

How do you know when electric current is flowing in a light bulb circuit?
You know if current is flowing in a bulb circuit because, if there is enough power (voltage times current), the bulb will illuminate. If there is current, but not enough power to illuminate the bulb, you will need to measure the current with an ammeter to see if there is any current.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
If the current flowing through an electric heater increases from 6 to 12 amp while the voltage remains the same the heat produced by the heater will be what?
Since power is current times voltage, doubling current while keeping voltage the same will double the power. Ignoring slight non-linearity, if the power doubles, the heat will double.
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
Why During transmission of power it is transformed as high voltage rather than high current how is this possible as current and voltage are directly proportional?
Voltage and current are actually inversely proportional to one another. The formula P=IV is what you need to look at here, where P is Power, V is voltage, and I is current. Rearranging the equation you will see that V = P/I. You can see that if you increase voltage, while holding power constant, current is reduced. Now, to your question. The losses on a transmission line are proportional to the current flowing on the line, so transmitting at high voltage (and hence low current) is beneficial as it reduces the amount of power that is lost due to resistance in the line itself.
What kind of relationship can be concluded about the voltage difference across a resistor and the current flowing through it?
POWER=VI. V=voltage I= current
How power is flowing when voltage and phase angle is maintained same?
Assume you are saying that the current and voltage are in phase and you want to know how power is affected. When Voltage and Current are in phase the Power Factor is 1 and you have maximum power being applied. When Voltage and Current are not in phase, Power Factor decreases from 1 toward zero.
Avacuum cleaner uses 800 w of power the voltage source is 100 v what is the current flowing through the vacuum cleaner?
Power = Voltage * CurrentIsolating current, we getCurrent = Power/Voltage, I = 800W/100V = 8 amps
How do I calculate wattage?
To calculate wattage, you need to multiply the voltage (V) by the current (I). The formula is: Wattage (W) = Voltage (V) x Current (I). This formula applies to electrical circuits where the voltage is known and the current is flowing.
What microwave oven uses 1200 W of power The voltage source is 120 V What is the current flowing through the microwave?
To find the current flowing through the microwave, you can use the formula: Power (P) = Voltage (V) x Current (I). Given the power is 1200 W and voltage is 120 V, you can rearrange the formula to solve for current: I = P / V. Therefore, I = 1200 W / 120 V = 10 A. The current flowing through the microwave is 10 amps.
How do you know when electric current is flowing in a light bulb circuit?

How do you find power in a circuit?
Power in a circuit can be calculated by multiplying the voltage (V) across a component by the current (I) flowing through it. The formula for power is: P = V x I. It is measured in watts (W).
How much power used on 600v?
To calculate power used on a 600V circuit, you need to know the current flowing through it in amperes. Then, multiply the voltage by the current to find the power in watts using the formula: Power (W) = Voltage (V) x Current (A). Without the current value, we cannot determine the power consumption.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
How voltage is 350kv to watts?
To convert voltage to watts, you also need to know the current in the circuit. The formula to calculate power (watts) is: power = voltage x current. As voltage alone is given, you would also need the current flowing through the circuit to accurately determine the power in watts. Without the current value, it is not possible to convert voltage directly to watts.
If the current flowing through an electric heater increases from 6 to 12 amp while the voltage remains the same the heat produced by the heater will be what?
Since power is current times voltage, doubling current while keeping voltage the same will double the power. Ignoring slight non-linearity, if the power doubles, the heat will double.
Why do power lines have a high voltage in order to minimize current and heat loss?
Power lines have a high voltage to reduce the amount of current flowing through them, which helps to minimize heat loss and energy waste during the transmission of electricity.
