What does bioelectrical impedance analysis do?
Bioelectrical impedance measures the total amount of water in the body, using a special instrument that calculates the different degrees of resistance to a mild electrical current in different types of body tissue.
What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground). In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
Relation between kva and fault level?
There isn't enough information here. Available short circuit fault level can be given as a KVA value for different types of faults, but I assume the questioner is looking for a relationshiop between (transformer?) KVA and available short circuit current - If my assumption is correct, there is no direct correlation without knowing the transformer positive and zero sequence impedances. If these are known, you can assume the source impedance is infinite, and calculate the maximum short circuit current through the transformer as follows: lowside fault current for a 3 phase fault on the lowside of the transformer: lowside kV (line to line) / (1.732 x per unit positive sequence impedance x scalar to real impedance), where scalar to real impedance is equivalent to lowside kV (line to line) ^2 / base kVA. For a L-G fault, do the same with zero sequence impedance.
Which two coaxial cables have characteristic impedance of 75 ohms?
RG-6 and RG-59 are the most common types
Is there any other current except AC and DC?
No. Alternating Current and Direct Current are the only two types of current.
What are the three types of opposition to current flow that impedance represents?
There is pure resistance, inductive reactance, and capacitive reactance.
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).

What are different types of current?
There are two types of current AC current DCcurrent
What are the types two types of electric current?
Alternating current and Direct current
What were the types of opposition to Hitler?
brown hair, brown eyes, and if you were a Jew
What are the two types of current?
If the question is about electric current, then types of currents are alternating current (AC) and direct current (DC).
Which two coaxial cables have characteristic impedance of 75 ohms?
RG-6 and RG-59 are the most common types
What current types are diodes used in?
Direct Current or DC
Discuss the role of the opposition parties in the British House of Commons?
There are two types of opposition parties in the House of Commons: Her Majesty's Loyal Opposition (sometimes referred to simply as the Official Opposition), and third opposition parties. The Official Opposition is thought of as a "Government-in-waiting", providing an alternative government to take over should the existing Government resign or be dismissed, with the Leader of the Official Opposition being an alternative prime minister.Third opposition parties are also responsible for holding the Government accountable, but are generally not thought of as a viable alternative government, and rarely have as much pre-eminence in Parliament as do the Official Opposition. (For example, the Official Opposition receives more time during question period than do the third opposition parties.)
