The amperage flowing through a wire is directly related to the load placed on the circuit, and has nothing to do with wire size, except that a larger wire will carry more amperage. Increasing wire size will not lower amperage but will allow the circuit to carry more amperage if the breaker is also increased in size.
No. Ohm's law tells us that V = IR. For a given load, R is constant, and thus the only way to reduce current is to increase voltage.
You can lower amperage by reducing the load on the motor (how much work it does), also you can increase the voltage, but the motor must be wired for the voltage increase or it will burn up.
Ampere = Volt / Ohms, so you either increase the voltage, or reduce the total resistance.
a stepdown transformer is used to reduce the voltage and limit the available amperage
It doesn't. Assuming the load stays constant when you reduce voltage you reduce current. Power is derived by multiplying current x voltage. If they are both going down power must decrease.
Either you increase the voltage, or you reduce the resistance.Either you increase the voltage, or you reduce the resistance.Either you increase the voltage, or you reduce the resistance.Either you increase the voltage, or you reduce the resistance.
depends on how low incoming ppower is unit will have min max allowable voltage on name plate but the lower the voltage the higher the amperage draw which can reduce life of compressor or even kill it
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
actually, when resistance decreases then voltage drop across resistor. will decrease. and excess current will through it. but as per the condition in this question, if current remains constant, losses due to voltage drop will reduce, further it will reduce heat losses, i.e. I*I*Rt. and hence temp. of resistance will decrease
To reduce power loss in the cable.
by using a step down transformer we can reduce voltage values to the desirable limilts.
To reduce voltage drop in a wire the wire size must be increased.
Reduce the voltage or increase the resistance
You reduce voltage in a DC circuit with a resistor. If the power demands are high, however, you may need a switching voltage regulator.
Generally the voltage is constant and current varies as per the load. Load can vary and hence current can vary. You are stating an abnormal situation, where in voltage increases while current remains constant. I am assuming a constant load situation then normally when voltage increases, the current tends to reduce since over all load remains same. If the voltage goes up beyond a limit the insulation fails and may lead to short circuit, equipment failure, shock and fatality
Use a voltage divider (see the related link). =========================
The voltage must reduce by the same factor - that is Ohm's law.
In cooking terminology, that is generally referring to cooking a liquid down - making it thicker and richer in flavor.
Number of turns in the secondary winding define the voltage. Change the number of turn to change the voltage.
making the copper wire thicker
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
Grid stations are the station which reduce the High Voltage to Low Voltage and increase the Current, the Current is Low and Voltage is High at the Generation Plant to reduce the energy losses during transmission of Electricity.
A: Any resistance added in series will reduce the current unfortunately will also reduce the voltage
Voltage is stepped up during transmission to reduce the power loss during transmission due to resistance. Power is a product of Voltage*Current, and losses due to resistance are directly proportional to the square of the current. Now when we increase the voltage , keeping the power constant, the subsequent current reduces.. thus in turn reducing the transmission losses.
