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
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.
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.
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
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
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.
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
To reduce power loss in the cable.
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
by using a step down transformer we can reduce voltage values to the desirable limilts.
