To calculate impedance (Z), use the formula ( Z = \frac{V}{I} ), where ( V ) is the voltage across the component and ( I ) is the current flowing through it. If you have the resistance (R) and reactance (X), you can also calculate impedance using ( Z = \sqrt{R^2 + X^2} ). The impedance current can be found by rearranging the formula to ( I = \frac{V}{Z} ). Ensure you use consistent units, typically volts for voltage and amperes for current.

What is percentage impedance?
In electrical engineering, the percentage impedance of a transformer is the voltage drop on a full load, which is expressed as a percentage of the specified rated voltage. It's measured by conducting a short circuit test.
What effects voltage per unit?
When doing per unit analysis, voltage and power are normally the independent values, while impedance and current are normally dependent. Check and see what voltage your generator is producing, and follow it through any transformers, converting it accordingly and write it down in each zone. Any time the voltage changes level, you have to recalculate what your per unit current and impedance are. Choose some X amount of power to be constant throughout the entire system. Z = impedance; V = voltage; S = complex power; I = current. (Z base) = (V base)^2 / (S base) (I base) = (V base) / (S base)
When is the voltage and current in a LCR series AC circuit in phase?
In an LCR series AC circuit, the voltage and current are in phase when the circuit is at its resonant frequency. At this frequency, the inductive reactance (XL) and capacitive reactance (XC) are equal, resulting in their effects cancelling each other out. Consequently, the total impedance of the circuit is purely resistive, leading to the voltage and current reaching their peak values simultaneously.
Plot a graph of voltage vs current for voltage values ranging from 10 V to 100 V in V steps for each of the following resistance values?
To plot a graph of voltage versus current for resistance values, you can use Ohm's Law, which states that (I = \frac{V}{R}). For voltage values ranging from 10 V to 100 V in 10 V steps, you would calculate the current for each voltage using different resistance values. For example, if the resistance (R) is 10 ohms, the current (I) at 10 V would be 1 A, at 20 V would be 2 A, and so on up to 10 A at 100 V. You would repeat this for each specified resistance, plotting the current on the y-axis and voltage on the x-axis to visualize the relationship.
When a series circuit containing resistance and inductive reactance is connected to a ac supply the current will?
The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.
How to calculate the current in a circuit?
To calculate the current in a circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V/R. Simply plug in the values for voltage and resistance to find the current flowing through the circuit.
How do you verify omh's law using multi tester?
if your looking for current (I) = voltage ./. resistance voltage (v) = current x resistance resistance (r) = voltage ./. current plug in your values calculate them then use meter to see if they match!
When looking for the resistance do you divide or multiply?
To find resistance using Ohm's Law, you divide voltage (V) by current (I). The formula is R = V/I, where R is resistance. So, if you have the voltage and current values, you divide the voltage by the current to calculate the resistance.
What is percentage impedance?

What the three type of opposition to current flow impedance represants?
I think it's only two types. Resistance, the real part of impedance, and reactance,the imaginary part. All possible values of impedance can be made from suitable amountsof each of these.If you absolutely must have three types, then you'll be relieved to hear that reactancecan be positive (inductive, voltage leading) or negative (capacitive, voltage lagging).
When is the voltage and current in a LCR series AC circuit in phase?

When a generator of internal impedance and operating at 1gigahertz feeds a load via a coaxial line of characteristic impedance 50 ohm then the voltage wave ratio on the feed line is?
For a voltage standing wave ratio (VSWR) of 1.0, the source impedance, load impedance, and transmission line characteristic impedance must be matched. To calculate actual VSWR, you need to know these three values. You're question only supplies one (50 ohm line). Review wikipedia's writeup on "standing wave ratio" to glean an understanding of what you're asking about.
What are the effects of Rs and Rl?
The values of Rs and Rl in a circuit impact the current and voltage levels within the circuit. Rs represents the source resistance affecting the input impedance, while Rl represents the load resistance affecting the output impedance. A variation in these values can cause changes in signal attenuation, power dissipation, and overall circuit performance.

120v how much current does a 1500w resistace heater draw?
Using the formula Power = Voltage x Current, we can calculate the current: Current = Power / Voltage. Plugging in the values, we get 1500W / 120V = 12.5A. So, a 1500W resistance heater would draw 12.5A of current at 120V.
