Electrical power = current x voltage
Current is in amps
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
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.
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.
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.
Power=Volts x Amps Unit for power is watts
The formula you are looking for is I = W (VA)/E. Amps = Watts/ Volts.
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
Amps = Watts/Volts, or Amps = Sq Root of Watts/Resistance.
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.
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.
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.
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.
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.
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
Divide Watts by Volts ; this gives you Amps.
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.
You can convert amperes by using the formula: Amperes = Watts / Volts. To find out how much current 'X' watt of electrical equipment at 'Y' volt consumes per hour, you would need to divide the wattage by the voltage to get the amperes, and then also consider the duration of the consumption in hours.
