Potential Difference: GCSE Physics Definition. ... This means that potential difference can be calculated using the equation. A battery or cell has a positive terminal at one end and a negative terminal at the other. An EMF or electromotive force is generated between the terminals. The e.m.f is the total amount of potential difference present ...

GCSE; OCR Gateway; Electric circuits - OCR Gateway Potential difference. Electrical current transfers energy around circuits. There are two different types of circuits – series and parallel.
A voltmeter must be connected in parallel with the component for which you want to know the potential difference. Resistance slows down the flow of electrical charges in a circuit. The units of resistance are Ohms (\Omega). Current, potential difference and resistance are related by the following equation: \color{aa57ff}{V=IR}
Potential Difference. Potential difference is also known as voltage, but at GCSE use the term Potential difference. Potential difference is measured in volts (V) and is a measure of the amount of energy per unit charge (J/C). 1 V = 1 J/C. For current to flow in a circuit, there needs to be a potential difference.
Where: power, P, in watts, W; potential difference, V, in volts, V; current, I, in amperes, A; Power is measured in Watts (W). 1W means 1J of energy transferred in 1 second. Question: Billy is using a lamp. The current in the lamp is 0.4A, and the potential difference across the lamp is 5V.
The normal operating voltage (potential difference) for a lamp is 6 V. Calculate how much energy is transferred in the lamp when 4200 C of charge flows through it. Answer: Step 1: List the known quantities. Voltage (potential difference), V = 6 V. Charge moved, Q = 4200 C. Step 2: State the equation linking potential difference, energy and charge
This “Voltage and Potential Difference” PowerPoint lesson is designed for AQA GCSE Physics students, providing a structured approach to understanding potential difference, how it is measured, and its role in electrical circuits. ... Apply the equation: V = E/Q where V is potential difference (volts), E is energy transferred (joules), and Q ...
T he potential difference (often referred to as voltage) from the power supply. The resistance of the components in the circuit; Electrical work is done when an electric current flows through a circuit. We can calculate the current, potential difference or resistance using the equation:
Electricity. What is Potential Difference or Voltage?. Potential difference (or p.d.) is another word for voltage. You can use either term to mean the same thing but most exam questions use potential difference rather than voltage.. The potential difference (voltage) of a power supply is an electrical pressure that causes a current to flow in a circuit. Doubling the supply voltage will double ...

Electricity - 2.2.3 Current, Resistance and Potential Difference (GCSE Physics AQA) Current, Resistance and Potential Difference Potential Difference Cells and Batteries. As we said above, cells or batteries are required to move charge around the circuit. They are like ‘electron pumps’. In a circuit you can have cells / batteries and ...
Calculate the potential difference through a resistor of resistance 10 Ω if there is a current of 0.3 A through it. Answer: Step 1: List the known quantities. Resistance, R = 10 Ω. Current, I = 0.3 A. Step 2: Write the equation relating resistance, potential difference and current. V = IR. Step 3: Substitute in the values. V = 0.3 × 10 = 3 V
Therefore across the lamp there is an electrical energy difference. The electrons entering the lamp have a higher electrical energy than the electrons leaving the lamp. This difference in electrical potential energy across the lamp is called a “POTENTIAL DIFFERENCE or p.d.”
