What is the formula to calculate load voltage?
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
What is the formula of ampere?
The formula for amperage is:I = V / RI = amperage, V = voltage, and R = resistance.Also amperage can be found by using the following formulas.I = P / V, Amps = Watts/VoltsI = sq root P/R, Amps = the square root of (power divided by resistance) watts/ohms.
How do you find power in a power equation?
To find power in a power equation, use the formula ( P = IV ), where ( P ) represents power in watts, ( I ) is the current in amperes, and ( V ) is the voltage in volts. If you have resistance instead, you can use ( P = I^2R ) or ( P = \frac{V^2}{R} ) depending on the known variables. Simply plug in the known values into the appropriate formula to calculate the power.
What if a video monitor draws 1.5 a at a voltage of 150 volts what is the power rating of the monitor?
To calculate the power rating of the monitor, you can use the formula ( P = V \times I ), where ( P ) is power in watts, ( V ) is voltage in volts, and ( I ) is current in amperes. For the given monitor, ( P = 150 , \text{volts} \times 1.5 , \text{amperes} = 225 , \text{watts} ). Therefore, the power rating of the monitor is 225 watts.
Unit of electric power determined by muliplying volts times amperes?
Power=Volts x Amps Unit for power is watts
How many amperes are in 400kVA at 220volts?
The formula you are looking for is I = W (VA)/E. Amps = Watts/ Volts.
Formula for watts and amps?
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?
The power consumed by the light bulb can be calculated using the formula P = I * V, where P is power in watts, I is current in amperes, and V is voltage in volts. In this case, the power consumed is 1.2 amperes * 12 volts = 14.4 watts.
How do you solve watts to amperes?
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
Formula for 7.5va convert into Amperes load comsumption?
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.
What is the formula for calculating power loss in a transmission line?
The formula for calculating power loss in a transmission line is Ploss I2 R, where Ploss is the power loss in watts, I is the current flowing through the line in amperes, and R is the resistance of the line in ohms.
How do you convert btu to ampere?
To convert BTUs (British Thermal Units) to amperes, you first need to convert BTUs to watts, using the conversion factor where 1 BTU/hour is approximately equal to 0.293071 watts. Then, you can use the formula ( I = \frac{P}{V} ) to find the current in amperes, where ( I ) is the current in amperes, ( P ) is the power in watts, and ( V ) is the voltage in volts. Simply divide the power in watts by the voltage to get the current in amperes.
What does volt times ampers equal?
Volt times amperes equals watts, which is the unit of electrical power. In this context, volts represent the electrical potential difference, while amperes measure the current flowing through a circuit. The formula is expressed as P (power in watts) = V (voltage in volts) × I (current in amperes). This relationship is fundamental in electrical engineering and helps in calculating the power consumption of devices.
What is the formula for calculating the power dissipated in a resistor, given the current flowing through it and the resistance value, known as the i2r power?
The formula for calculating the power dissipated in a resistor, known as the i2r power, is P I2 R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.
What is the formula to calculate load voltage?
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
How many Watts in 200 Volt?
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 Watts.
