Assuming the zero state output of the DAC is 0 volts, then 4095 steps of 8mv would yield a full scale output of 32.76 volts. The resolution is one part in 4096, or 2.44 percent. An input of 010101101101 is 1389. Multiply that by 8mv, and you get 11.11 volts.
In the CEC (Canadian Electrical Code) voltage drop for feeders is stated in rule 8-102. Voltage drop in an installation shall not exceed 3% in a feeder or branch circuit. This percentage may differ in the NEC (National Electrical Code).
1. The sum of the component voltage drops in a series circuit is equal to the voltage at the source.Vs=V1+V2+...+Vn (s=source, n=total number of voltage drops in the circuit)2. The greater the resistance imposed by a component, the greater the voltage drop across it.Larger resistor=larger voltage drops, Smaller resistor=smaller voltage drops3. In a series circuit, the percentage of resistance contributed by a component is equal to the percentage of voltage dropped by that component.
Nominal voltage is the 'named' voltage -for example, the nominal supply voltage in the UK is 230 V. But this is not necessarily the actual voltage at a particular time. A nominal voltage is normally expressed together with the percentage by which it is permitted to vary from that stated value. For example, in the UK, the nominal voltage is expressed as: 230 V +10% / -6% --in other words it is allowed to vary between 216.2 and 253 V.The term, operating voltage, isn't actually defined anywhere, but is usually taken to mean the actual voltage supplied to a device at any particular instant, and this should always fall within the allowable range of the supply system's specified nominal voltage. The operating voltage can be found simply by measuring it with a voltmeter.
Percentage reactance of a transformer (or in general, a circuit) is the percentage of phase voltage drop when full load current flows through it, i.e %X=(IX/V)*100. Now Short Circuit Current is V/X So short Circuit current is I*(100/%X).
Impedance (Z) voltage is the amount of voltage applied to the primary side to produce full load current in the secondary side. It is usually listed on the transformer nameplate, expressed as a percent, and measured by conducting a short circuit test.
With stun guns voltage is used to cause pain to the attacker and only a percentage of the time will he or she fill it.
In the CEC (Canadian Electrical Code) voltage drop for feeders is stated in rule 8-102. Voltage drop in an installation shall not exceed 3% in a feeder or branch circuit. This percentage may differ in the NEC (National Electrical Code).
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.
The term, 'percentage impedance', is a little misleading, as it is defined as 'the value of primary voltage that will cause rated current to flow in the secondary winding, expressed as a percentage of the rated primary voltage'. So, the test is carried out as follows: the secondary winding is short-circuited through an ammeter capable of reading the rated secondary current. A variable voltage is applied to the primary winding. The primary voltage is gradually increased until the ammeter indicates rated secondary current. That primary voltage is then expressed as a percentage of the rated primary voltage -and that value is the transformer's 'percentage impedance'.
Percent Regulation is the regulation expressed as a percentage is a figure of merit used to specify the performance of a voltage regulator.
The volatge regaulation be calculated by calculating the percentage difference between volatge at no load and voltage at full load

percentage regulation is defined as [{v(no load)-v(full load)}/v(full load)]*100% it gives the variation of output dc voltage(voltage across load) with variation in load resistance
The answer is different depending on the supply voltage because the allowable volt drop is a percentage of the supply voltage.
The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage.It is also the percentage of the normal terminal voltage required to circulate full-load current under short circuit conditionsThe impedance is measured by means of a short circuit test. With one winding shorted, a voltage at the rated frequency is applied to the other winding sufficient to circulate full load currentZ% = Impedance Voltage x 100Rated Voltage
Ripple, in DC power supplies, is technically unitless. Ripple voltage is specified in Volts/Volt, or a percentage. For example, a 12VDC power supply with 120mV (pk-pk) of ripple voltage is (0.12/12) = 1% ripple voltage.
When doing voltage drop calculations the voltage to the connected devices should not drop below 3 % of the supplied voltage. <<>> "Most" appliances? that a tough one there is no standard. A few percent is no trouble, different appliances have different tolerances: no generalizations are possible.
