What else can I help you with?
If resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
Is potential difference directly or inversely proportional to resistance?
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
What is produced first current or voltage?
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
What is the difference between conventional current and electric current?
Conventional current is the flow of positive charge from higher potential to lower potential, while electric current is the flow of electrons from lower potential to higher potential.
If two potential energy were pointing in different directions will there be a current between two points?
Current will flow if there is a difference of potential energy and a path between those points.
The electrical potential energy in one point in a circuit is greater than the electrical potential energy at another point. Will there be a current between the two points Explain.?
Yes, there will be a current between the two points because a potential difference (voltage) exists between them. This potential difference will cause charges to flow from the higher potential energy point to the lower potential energy point, creating an electric current.
Can potential difference ocur without current?
Yes. This is the build up of charge. The difference in charge, aka the potential difference, is the driving force that causes current to flow. The third law of thermodynamics is in action when the circuit is completed and the current flows between two point as a result of the potential difference between those two points. (p.s. I am an American girl)
Will there be a current between the two points if the electrical potential energy at one point in a circuit is greater than the electrical potential energy at another point?
Yes, there will be a current flowing between the two points if there is a difference in electrical potential energy. This potential difference causes charges to move and create an electric current to balance out the potential energy.
Define the 'potential difference between the ends of a conductor'?
Potential difference between the ends of a conductor refers to the electrical energy difference per unit charge between two points in the conductor. It is commonly known as voltage and is measured in volts. A potential difference is necessary for the flow of electric current in a conductor.
What is basic difference between Potential meter and rheostate?
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
What is the term for the potential difference in a charge between two points in current path?
capacitance
What is the term for the potential difference in a charge between two point in a current path?
voltage
