What is meant by heavy current?
Heavy current: high voltage, high current, high power, but the low frequency. The main issue considered is to decrease power loss and enhance efficiency. Heavy current is generally applied for mains electricity systems and lighting systems such as air-conditioning, sockets, power cabling, and high-voltage wiring.
What is a high current of electricity?
define high voltage as above 1000 V for alternating current, and at least 1500 V for direct current. In the United States, the American National Standards Institute (ANSI) establishes nominal voltage ratings for 60 Hz electric power systems over 100 V.
What causes high current flow?
Examples. A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.
What happens if current is too high?
If the current is too large, the heat loss can damage the circuit, burn the resistors, or even burn the surrounding objects. Even with circuits designed to prevent such situations, accidents can happen, such as when wires touch each other unexpectedly.
What does a heavy current electrical engineer do?
A qualified Electrical Engineer in Heavy Current will be responsible for the designing and planning of different energy sources to feed into electricity grids, which in turn is used for a variety of different uses where electricity is required.

What kills you high voltage or high current?
An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
Can you have low voltage and high current?
Various combinations of high/low voltage/current are used. For example, low voltage and high current is used to run the starter motor in your car. It’s only 12V, but can exceed 100A. However note the drawback, which is thick cables going to the starter.
How much current is too much?
While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and 200 mA (0.1 to 0.2 amp) are lethal.
Are electrical engineers in high demand?
Overall, electrical engineers are in demand. According to the Bureau of Labor Statistics, electrical engineer jobs are projected to grow by 9% in the coming years. There is always a need for entry-level engineers as older ones leave the field.
How does a conductor create an electric current?
Conductors allow for charge transfer through the free movement of electrons. The flow of electrons inside the conducting material or conductor generates an electric current. The force that is required to drive the current flow through the conductor is known as voltage.
How is the current of an electric current measured?
The electric current is measured in ampere. One ampere of current represents one coulomb of electric charge moving past a specific point in one second. 1 ampere = 1 coulomb / 1 second
What is the difference between electrical pressure and current?
Electrical pressure is the difference in electrical potential between two points with or without current flow. Without current flow it known as an EMF (electro motive force E) with current flow it is described as a potential difference (pd V). Both are measured in volts (symbol V).
Why is current important in an electronic circuit?
Electric current is an important quantity in electronic circuits. We have adapted electricity in our lives so much that it becomes impossible to imagine life without it. Therefore, it is important to know what is current and the properties of the electric current. We know that electric current is the result of the flow of electrons.
