Current is the amount of electriticy that flows through a conductor. The electric current is determined by two factors: The voltage applied to the circuit, and the diameter ( circular area in mm2) of the wire (conductor). More voltage, more current, the same voltage in a smaller diameter of the wire = less current. / less voltage = less current. / smaller diameter of the wire = more resistance> less current. Load inserted in the circuit has a resistance measured in Ohms = more resistance of the load ( a lamp, for example) = less current. / larger diameter of the wire= more current, because it has less resistance. / All can be easily calculated using the Ohm Law =
The interchangeability of the equation may be represented by a triangle, where V (voltage) is placed on the top section, the I (current) is placed to the left section, and the R (resistance) is placed to the right. The line that divides the left and right sections indicate multiplication, and the divider between the top and bottom sections indicates division (hence the division bar).
Direct currrent flows only in one direction. Alternating current moves back and forth, usually 50 or 60 cycles per second. It means that one pole is negative or positive 50 or 60 times per second.
In electronics, other forms of electric current include the flow of electrons through resistors or through the vacuum in a vacuum tube, the flow of ions inside a battery or a neuron, and the flow of holes within a semiconductor.

What are two types of electrical currents?
Direct current (DC) flows in one direction and is commonly used in batteries and electronics. Alternating current (AC) changes direction periodically and is used in homes and most electrical grids for its ability to be easily transmitted over long distances.
What 2 types of currents do you commonly refer to with electricity and what do they stand for?
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
What are the three types of ocean currents?
The three types of ocean currents are surface currents, deep currents, and tidal currents. Surface currents are driven by winds, deep currents are driven by density and temperature differences, and tidal currents are driven by the gravitational pull of the moon and sun.
What is the sum of currents is known as?
The sum of currents in a circuit is known as total current, which is the combined flow of all individual currents passing through the circuit components. This total current is conserved in a series circuit where it remains constant throughout the circuit.
What cold currents near coastlines might indicate sites of upwelling?
Cold currents near coastlines often indicate the presence of upwelling. This is because upwelling brings cold, nutrient-rich waters from the ocean depths to the surface, leading to colder surface currents. Some examples of cold currents near coastlines that are associated with upwelling include the California Current, the Benguela Current, and the Canary Current.
What are the two types of current?
If the question is about electric current, then types of currents are alternating current (AC) and direct current (DC).
What are the two types of ocean currents?
deep currents streamlike movement of water that flow very slowly along the ocean floor. surface current can influence the climate of land are they flow past.
What are two types of currents?
Direct current and alternating current
What is warm ocean current and how many types of warm ocean current are there?
discuss warm ocean currents
What types of currents are on Earth?
I know four ,but I'm pretty sure this could help. I know water currents, air currents, heat currents, and electric currents. This would probably go along with water current, but anyways there is also a ocean current. . :D
Are The Benguela Current the Peru Current and the California Current warm currents .?
they're cold currents
What are two types of ocean current?
killer whale and a shark
What are two types of electrical currents?
Direct current (DC) flows in one direction and is commonly used in batteries and electronics. Alternating current (AC) changes direction periodically and is used in homes and most electrical grids for its ability to be easily transmitted over long distances.
What are two largest ocean currents?
the loser current and this web site is no help current
Plural word for current?
The plural of current is currents.
What are the basic 2 types currents?
You can have electrical currents, or currents in fluids such as water or air.
What 2 types of currents do you commonly refer to with electricity and what do they stand for?
the two types of electrical current are AC which stands for Alternating current and DC which stands for direct current. Battery current is direct current. The electrons in alternating current flow one way and then flow in the opposite direction.
