WebPotential Difference (also known as Voltage) Potential difference, also commonly referred to as voltage, is an important concept to understand. In these videos I'm using the rope loop model to explain this. The current through a component depends on both the resistance of the component and the potential difference across. WebPotential difference is measured in volts (V). This is the same as a Joule per coulomb (J C-1) If a bulb has a voltage of 3 V, every coulomb of charge passing through the bulb will …

WebAn ohmic conductor will have a current-voltage ( I–V) graph that is a straight line through the origin. An I-V graph for an ohmic conductor is a straight line graph through the origin. Reversing the potential difference (and direction of the current) makes no difference to the shape of the line, the potential difference and current values ... WebSep 15, 2015 · Specification reference GCSE Combined Science: Synergy; Outcome 1 ... The term ‘potential difference’ will not be used. 6.2.1.3. 4.7.2.2. The resistance of a component is a measure of how difficult it is for an electric current to pass through it. Calculations of resistance will not be required, nor will the units of resistance. ...

WebJun 30, 2024 · Potential Difference Electro-Motive Force (EMF) In a closed circuit, the difference of potential between any two points is termed as potential difference. The … WebPotential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. Learn about and revise electrical circuits, charge, current, power and resistance …

WebMay 15, 2015 · This is where it gets tricky! You may previously have used the term 'voltage' but now you need to understand the difference between the e.m.f. of a supply and the p.d. across a component. This also shows you where to put a voltmeter in a circuit and the definitions of all key terms. Pl ... WebThe size of the current is the rate of flow of electrical charge. Electric charge is carried by electrons. In order for electric current to flow through a circuit, a source of potential difference (like a battery or a cell) must be included. Current Equation. You must be able to remember and apply this equation: Charge flow = current x time

WebVoltage drops and gains, later referred to as potential drops and rises, by analogy with gravitational potential difference, might also best be excised from the classroom for now. Indeed, the whole idea of potential difference is one that is hard for post-16 students. We'd suggest leaving the hills analogy to then.
