- The general definition of work is "force acting through a distance" or W = F \cdot d W = F ⋅d. In electric field notation, W = q E \cdot d W = qE ⋅d Energy is "the ability to do work." When an object has energy, it has the ability to do work. When a force does work on an …
Basic electrical quantities: current, voltage, power - Khan Academy
- https://www.khanacademy.org/science/physics/circuits-topic/circuits-resistance/a/ee-voltage-and-current
- The electric power consumed by a device may be calculated by using either of the two expressions P=I^2 R or P=V^2 /R. The first expression indicates that it is directly proportional to R whereas the second …

- Mathematically, the voltage can be expressed as, Where, work done is in joules and charge is in coulombs. We can define the …
What is Voltage? | Fluke
- https://www.fluke.com/en-us/learn/blog/electrical/what-is-voltage
- Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is …
How to Calculate Voltage Across a Resistor (with Pictures)
- https://www.wikihow.com/Calculate-Voltage-Across-a-Resistor
- Voltage across R 2 = V 2 = ( 1.2A ) ( 3Ω) = 3.6 volts. Voltage across R 3 = V 3 = ( 1.2A ) ( 5Ω) = 6.0 volts. 6 Check your …
