It depends by how much it changes. Power (watts) = current (amps) x voltage
If the current halves and the voltage doubles, the power won't change. But if the current is cut in half and the voltage only goes up by a little bit the watts will go down. If the current only goes down a little bit but the voltage doubles, then the watts will go up.
To calculate the wattage of a device, you need to know both the current (in amperes) and the voltage (in volts). If the voltage is not provided, you cannot accurately calculate the wattage. In this case, with only the current (4 A) given, you cannot determine the wattage without knowing the voltage as well.
To find the actual wattage of an electrical component, you can calculate it by multiplying the voltage across the component by the current flowing through it, using the formula Watts = Volts * Amps. Alternatively, you can refer to the product specifications provided by the manufacturer, which usually list the wattage of the component.
To convert wattage to kilovolts, you typically need more information. Wattage is a measure of power, while kilovolts are a measure of voltage. The conversion will involve using the formula P (watts) = V (volts) x I (current), where V is the voltage in kilovolts. By rearranging the formula to solve for V, you can convert wattage to kilovolts if you know the current as well.
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
To calculate the voltage (V) from wattage (W), you can use the formula: V = W / A, where A is current in amperes. However, without knowing the current, you cannot determine the voltage directly from the wattage alone. If you know the current, you can substitute that value into the formula to find the voltage for 9 watts.
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.
That depends on the voltage V. Wattage P = amperage A times voltage V.
wattage is nothing but power product of current and voltage p=v*i
To calculate the wattage of a device, you need to know both the current (in amperes) and the voltage (in volts). If the voltage is not provided, you cannot accurately calculate the wattage. In this case, with only the current (4 A) given, you cannot determine the wattage without knowing the voltage as well.
If running at 110V, that is 10Amps. Wattage = Voltage x Current Current = Wattage / Voltage - Neeraj Sharma
Wattage = Outage Voltage + Outage Wattage
Devide the wattage by the voltage
The wattage of the drill can be calculated by multiplying the voltage (120 V) by the current (4 A). Wattage = Voltage x Current Wattage = 120 V x 4 A = 480 watts. Therefore, the wattage of the drill is 480 watts.
wattage is voltage and amperage multiplied. example V/A=W or 120v x 20a=2400 watts
To find the actual wattage of an electrical component, you can calculate it by multiplying the voltage across the component by the current flowing through it, using the formula Watts = Volts * Amps. Alternatively, you can refer to the product specifications provided by the manufacturer, which usually list the wattage of the component.
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
