depends on the simple circuit. please describe it.
There is a potential difference (voltage) between two points and a path for electrons to travel from an area of low potential (negative) to an area of high potential (positive). Note the direction of "current flow" is opposite the direction of electron flow. In other words current flows from positive to negative. In a circuit involving only a resistor, the current flowing in the circuit is given by I=V/R where I = current, V= voltage, and R=resistance.
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
An electric current through a resistive circuit can be increased by decreasing the resistive load or increasing the voltage of the circuit.
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
To determine the potential difference in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). By measuring the current flowing through the circuit and knowing the resistance of the components, you can calculate the potential difference.
Voltage, also known as potential difference, is the force that drives electrical current in a circuit. The higher the voltage, the greater the potential difference and the more electrical energy is transferred in the circuit.
That would be DC or Direct Current.
Current flows in a circuit when there is a difference in electronic potential between two points.
some resistance and potential difference
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
Electric potential difference or voltage is the force that keeps current flowing in a circuit. The potential difference creates an electric field, which in turn exerts a force on the charged particles in the circuit, causing them to move and establish a current flow.
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
The terminal potential difference decreases when the current in the circuit is increased due to the internal resistance of the power source. As the current increases, the voltage drop across the internal resistance also increases, leading to a decrease in the terminal potential difference available to the external circuit. This is described by Ohm's Law, V = E - Ir, where V is the terminal potential difference, E is the electromotive force of the source, I is the current, and r is the internal resistance.
In a series circuit, the total potential difference provided by the power source is divided among the components in the circuit. As current flows through each component, there is a voltage drop across each one. This results in a reduction of potential difference as you move along the circuit.
Yes, in a circuit with no current draw, the potential difference is the same at every point in the circuit. This is due to the conservation of energy principle in electric circuits.
Not necessarily. The two points with potential difference, will have to be connected via a conductor, for current to flow.Provided that a circuit exists, then current WILL flow.
