What is reactive current?
current that does't use in power measurement is called reactive current.
How do you calculate short circuit current?
A short circuit = 0 ohm, from this one can use ohms law to calculate the current, that is E/R voltage divided by resistance as in this instance your resistance is zero and you can't divide by zero so your current will be infinit. In other words if your power supply is large enough to supply 200 amp, your current on a short circuit will be 200 amp.
How do you calculate power use for a home power generator?
Click the link. There you can figure the size generator you need.
What is the equation used to calculate the resistance current or voltage?
S = Apparent Power P = Real Power [Negative for supplied power, positive for absorbed power] Q = Reactive Power [Positive for lagging or inductive loads, negative for leading or capactive loads] Fp = Power Factor [Specified as lagging or leading for inductive or capacitive loads respectively] V = Voltage I = Current * = (Conjugate) < = 'At an angle of' For DC cases: |P| = P = V x I = V^2 / R = I^2 x R For AC cases: S = V x I* = |S| < arccos(Fp) |S| = |V| x |I| |P| = |S| x Fp |Q| = sqrt(|S|^2 - |P|^2)
What is the formula for phase angle?
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.
Why you take complex conjugate of phasor current in complex power?
In electrical engineering, when calculating complex power (S = VI*), we use the complex conjugate of the phasor current (I*) because it ensures that the power calculation reflects the correct direction of power flow. The complex conjugate accounts for the phase difference between voltage and current, allowing us to separate real (active) power and reactive power components. This convention aligns with the mathematical properties of complex numbers, ensuring that the resulting power values are consistent with physical interpretations in AC circuits.
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How can you calculate the current an appliance can use?
To calculate the current an appliance can use, divide the power rating of the appliance (in watts) by the voltage it operates on (in volts). The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts). This calculation will give you the maximum current the appliance can draw under normal operating conditions.
How do yo calculate electric power and energy use?
Power = voltage x current Number of power in volts
What formula would you use to calculate the current drawn in a low beam headlamp circuit?
Since power is the product of voltage and current, you will need to find out the power rating of the headlamp when on low beam. To find the current, divide the power of the lamp by the voltage (12 V).
How can calculate the power of contactor if you know the amper is 30 a?
To calculate the power of a contactor when you know the current (in this case, 30 amps), you can use the formula: Power (P) = Voltage (V) × Current (I). First, determine the voltage at which the contactor operates (e.g., 120V, 240V, or 480V). Then, multiply the voltage by the current: for example, at 240V, the power would be P = 240V × 30A = 7,200 watts (or 7.2 kW).
How do you calculate pka?
To calculate pKa, you can use the Henderson-Hasselbalch equation: pKa = pH + log([A−]/[HA]), where [A−] is the concentration of the conjugate base and [HA] is the concentration of the acid. Alternatively, you can look up the pKa value in a table or use a chemical database.
How can one determine the pH of polyprotic acids?
To determine the pH of polyprotic acids, one can use the stepwise dissociation constants of each acidic proton and calculate the concentrations of the acid and its conjugate base at each stage of dissociation. By considering the equilibrium concentrations of the acid and its conjugate base, one can then use the Henderson-Hasselbalch equation to calculate the pH of the solution.
An electric iron is marked 240 voltagen 1200 w calculate the current flow through the electric iron?
To calculate current flow, use the formula: Current (I) = Power (P) / Voltage (V). Substituting the given values, the current flowing through the electric iron would be I = 1200W / 240V = 5A.
How to calculate the average power in labview?
If you are talking electrical power, take a sample as an array of double of the current, same for voltage, use the RMS block on both I, V and multiply the result.
How can you calculate a current stock pricing?

How do you calculate force and power for electromagnet?
To calculate the force produced by an electromagnet, you can use the formula: Force (N) = magnetic field strength (T) x current (A) x length of the conductor (m). Power can be calculated using the formula: Power (W) = current (A) x voltage (V). Make sure to consider the properties of the specific electromagnet and the materials involved in your calculations.
