Cables aren't perfect conductors, they have a bit of resistance. This resistance cacuse a certain voltage drop. But the drop isn't proportional to the voltage running through the cable, so at lower voltages the proportion lost to internal resistance in the cable will be bigger than at higher voltages.

What does EKG result low voltage mean?
A low voltage EKG means the amplitude of the QRS waves on the EKG are lower than would be expected. COPD, obesity, and pericardial effusions can cause low EKG voltages, amongst other causes.
How many volts is low voltage?
Low voltage by definition means any voltage from 31 to 750 volts inclusive.
What is the difference between high and low current?
The difference between low voltage and high voltage for the same size cable is that cable size affects current carrying capacity, while power is voltage times current. As a result, the same size cable can transfer more power at high voltage than at low voltage. This is why utility power transmission and distribution systems use high voltage. A typical transmission voltage in the US might be 69 kv, 138 kv, even 345 kv, and a typical distribution voltage in the US might by 13.2 kv.
How many volts is low voltage electricity?
Low voltage by definition means any voltage from 31 to 750 volts inclusive.
What is a distribution voltage?
An intermediary voltage between high voltage and low voltage. I previously wrote 69kV and 34.5kV were distribution level voltages. This is not true, these are generally considered "sub Transmission" level. Anything below ~ 33kV and above ~1kV is considered distribution. Common voltages of this range I've seen are 2.4kV, 12.5kV, 13.8kV.
What causes high and low currents?
In electricity? High voltage ,high currents. Low voltage, low currents.
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
How a transformer is so important?
Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.
What causes of a lean exhaust?
because of low battery voltage
What causes transmission slippage on a ford Taurus?
check your transmission fluid, if it is low it will slip
Why is the voltage drop large in a high voltage transmission line?
The length of the wire causes resistive load to be distributed along line. This accumulated resistance causes the voltage drop.AnswerThe voltage drop along a high-voltage transmission line isn't large in relation to the operating voltage of the line. One of the advantages (there are many) of using high voltages is that, for a given load, the line current is relatively low -so the voltage drop along the line is also relatively low.
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
What are grid station?
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.
What causes a automatic transmission to shift hard?
Possibly low fluid.
High voltage current is needed for transmission but is low voltage is more useful?
A: Power transmission is in the range of 500 kilo volts as someone can tell the hi towers are far above ground and each phase is separated by ceramic insulators. Low voltage is necessary to manage these power safely to homes and business. That is why transmission becomes distributions and finally local power to us.
What causes maximum secondary coil voltage?
I would hazard a guess and say that it is a bad coil.
What does DTC pending code P0562 mean?
System voltage low(tcm).transmission control module
