Electrical current generally increases as voltage increases due to a need for increased capacity. This is directly controlled from the transmission side but varies based on the overall load.
What else can I help you with?
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.
What happens to the electric current in a wire as voltage is increased?
As voltage is increased, the electric current in a wire also increases because the relationship between voltage, current, and resistance is described by Ohm's Law (V = IR). If resistance remains constant, a higher voltage will result in a higher current flowing through the wire.
What is the relationship between power, current, and voltage in an electrical circuit?
In an electrical circuit, power is the product of current (the flow of electric charge) and voltage (the force that drives the current). The relationship between power, current, and voltage is described by the equation P I x V, where P is power, I is current, and V is voltage. This equation shows that power increases when either current or voltage increases in a circuit.
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
Why the current increases rapidly at breakdown voltage?
The current increases rapidly at breakdown voltage due to the phenomenon of avalanche breakdown in semiconductor materials. At this voltage, the electric field strength becomes sufficient to ionize atoms, creating free charge carriers. These carriers are accelerated by the electric field, leading to further ionization and a chain reaction that dramatically increases current flow. This process results in a sudden and significant rise in current, often leading to device failure if not controlled.
What is the relationship between voltage and the electric field in a given system?
In a given system, the relationship between voltage and the electric field is that the electric field is directly proportional to the voltage. This means that as the voltage increases, the electric field strength also increases. Conversely, if the voltage decreases, the electric field strength will also decrease.
What happens to voltage when resistance increases?
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
What does the current vs voltage graph reveal about the relationship between current and voltage in the given circuit?
The current vs voltage graph shows that there is a linear relationship between current and voltage in the given circuit. This means that as voltage increases, the current also increases proportionally.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
What is the relationsip between current and voltage?
Ohm's law says Voltage = Current x Resistance. As voltage increases, currrent increases proportionally with a fixed load.
