5% from source to farthest load.
3 % (+ or -) on LT side is generally permissible. (in India)
Appliances at home have designated voltage e.g. 220 V or 110 V. When the voltage is dropped, the appliances try to run at their designated power in kW as usual. To keep the power same, current is increased (P = VI). This increase in current can burn the most delicate part of the appliances if the low voltage is experienced persistently.AnswerA drop in supply voltage results in a drop in the power of appliances. For fixed-resistance devices, a 10% drop in voltage results in approx, 18% drop in power.
the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................
A brownout refers to the drop in voltage in an electrical power supply system. A blackout, on the other hand, is the complete loss of electric power in an area.
The answer is different depending on the supply voltage because the allowable volt drop is a percentage of the supply voltage.
Your voltage shouldn't drop after a storm, unless there's widespread disruption to the electricity supply.
You shouldn't really have much voltage "drop". If you do, it usually means that there is a poor connection somewhere along your service line or inside wiring. Any significant amount of voltage drop can mean that you are at risk of a fire. On the other hand, line voltage into a house may not actually be 240 VAC. Measure the ACTUAL voltage with everything turned off, then see where it goes when you start turning things back on. The difference between the supplied voltage and the load voltage is the voltage "drop".
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming
To answer this question a supply voltage must be stated. Also the wattage of the lamps is needed.
For a lamp to operate at its rated power, it must be subject to its rated voltage. The lower the voltage, the lower the resulting power. In fact, a small drop in voltage will cause substantial drop in power. Higher 'wattage' lamps have lower resistance values than lower 'wattage' lamps.So, if you put two lamps in series, the greater voltage drop will appear across the lamp with the greater resistance. In your example, that means the 100-W lamp will be subject to the greater voltage drop, and its loss of power will be less than that of the 200-W lamp. So the lower power lamp will be the brighter of the two.
The question can't be answered without knowing what the voltage is. That is because the allowed voltage drop is 5% of the supply voltage, so you need to know the supply voltage. Then the wire calculation aims to find out what the minimum size of wire is that produces that voltage drop or less.
