To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.

What device creates a potential difference in an electric circuit?
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
What is the difference between voltage and electric potential, and how do they relate to each other in an electrical circuit?
Voltage is the measure of the electric potential difference between two points in an electrical circuit, typically measured in volts. Electric potential, on the other hand, refers to the electric potential energy per unit charge at a specific point in the circuit. In simpler terms, voltage is the potential difference between two points, while electric potential is the potential energy at a single point. In an electrical circuit, voltage is used to describe the potential energy difference that drives the flow of electric current from one point to another.
Which creates a potential difference in an electric circuit?
A potential difference in an electric circuit is created by a voltage source, such as a battery or a power supply. This causes electrons to flow from higher potential to lower potential, creating an electric current in the circuit.
What is the voltage across the resistor at this instant in the circuit where Vab is measured?
The voltage across the resistor at the instant in the circuit where Vab is measured is equal to the potential difference between points A and B.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.

What is the formula for calculating the potential difference across a capacitor in an electric circuit?
The formula for calculating the potential difference across a capacitor in an electric circuit is V Q/C, where V represents the potential difference, Q is the charge stored on the capacitor, and C is the capacitance of the capacitor.
What is the relationship between voltage and potential difference in an electrical circuit?
Voltage and potential difference are essentially the same thing in an electrical circuit. Voltage is the measure of potential difference between two points in a circuit. In other words, voltage is the force that pushes electric charges through a circuit, and potential difference is the measure of this force.
True or false are charges in an electric circuit flow because of a difference in electrical potential energy?
True. Charges in an electric circuit flow because of a difference in electrical potential energy. This difference causes the charges to move from areas of higher potential energy to areas of lower potential energy, thus creating an electric current.
What is the dimension of potential difference?
The dimension of potential difference is voltage, which is measured in volts (V). Voltage represents the difference in electric potential energy per unit charge between two points in an electric circuit.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
