Let’s look at potential difference. Potential Difference. The potential difference (otherwise known as voltage) is the difference in energy between two components of a circuit. The higher the difference is, the higher the potential difference. Remember, some people may call this ‘voltage‘ instead of ‘potential difference’ We measure ...

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

Potential difference is measured in Volts. The symbol we use is ‘V’. A voltmeter is the device we use to measure the potential difference. Voltmeters are added to a circuit in parallel. Voltmeters measure the potential difference between two points.

The topics covered within these lessons include: Current and charge Potential difference Electrical circuit symbols Resistance and Resistors Circuit devices Series and parallel circuits Circuit calculations Energy and power in circuits All of these lesson presentations and accompanying resources are detailed and engaging and contain regular ...

Note: sometimes you will see the word voltage used instead of potential difference. The device for measuring current (I) is called the ammeter. It’s important to know, both for GCSE and A-Level, that the resistance of an ammeter needs to be very low. The device for measuring potential difference (p.d. or V) is called the voltmeter.

Direct. A direct potential difference is in one direction only.. This means that when the power source provides a direct potential difference a direct current will flow, this means that the current flows in only one direction around the circuit.. conventional current circuit diagram, showing the direction of conventional current. The direct current will flow from the positive terminal of the ...

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

In GCSE Physics, potential difference refers to the difference in electric potential energy between two points in an electric circuit. This difference in potential energy creates a force that causes electric charges to flow through a circuit, producing an electric current.

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 ...
