A switch controls the flow of the circuit by making or breaking the connection, so you get full flow or nothing.

In electronics, vacuum tubes or semiconductors, can also be used to control the flow by varying amounts.

How can one determine the potential difference in a 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.


What is the relationship between voltage, potential difference, and electrical energy in a circuit?

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.


Why does the potential difference change in a series circuit?

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.


What is the potential difference in electricity?

Potential difference, also known as voltage, is the force that drives the flow of electric current in a circuit. It is measured in volts and represents the energy per unit charge available to a charge to move in an electric field. A higher potential difference leads to a greater flow of current in a circuit.


How can you calculate the potential difference between two points in a circuit?

To calculate the potential difference between two points in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). The formula is V I x R. By knowing the current flowing through the circuit and the resistance between the two points, you can calculate the potential difference.

What type of current has steady potential difference across a circuit?

That would be DC or Direct Current.


When does current stop flowing in a circuit?

Current flows in a circuit when there is a difference in electronic potential between two points.


What happens to current in a simple circuit as potential difference is increased?

depends on the simple circuit. please describe it.


What conditions are necessary for a current to be present in a circuit?

some resistance and potential difference


Does potential difference change with change in resistance?

Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.


What kind of force keeps current flowing in a circuit?

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.


How does voltage produce current?

Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.

Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?

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.


If there are 2 points with different potential energy will there still be an electrical current through the circuit?

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.
