14 Νοε 2020 · The potential difference or voltage $V$ between two points is defined as the work required per unit charge to move the charge between the two points, or $V=W/Q$. When work is done to move change between two points there is a change in electrical potential energy of the charge.
The law of demand states that a higher price leads to a lower quantity demanded and that a lower price leads to a higher quantity demanded. Demand curves and demand schedules are tools used to summarize the relationship between quantity demanded and price.
12 Σεπ 2022 · The electric potential difference between points A and B, \(V_B - V_A\) is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta .
Potential difference is measure in volts (V) The potential difference is the difference in the electrical potential across each component: 5 volts for the bulb (on the left) and 7 volts for the resistor (on the right)
19 Φεβ 2022 · Based on Coulomb’s law of charge, in formula v=Ed, E is the electric field between both the plates, and d is the distance between the two plates. v=W/q, where ‘w’ is the work done to transport the particle from one location to another, v is the potential difference between both the plates, and q is the charge of the particle. In v=w/q, we ...
Q.What potential difference is required to do 100 J of work to carry a charge of 10 C between two points? Solution: Given, work done (W) = 100J. Charge (Q) = 10C. Potential difference (V) =? V = W/Q. V = 100 J ÷ 10 C = 10 V
The law of demand states that when the price of a product goes up, the quantity demanded will go down – and vice versa. It's an intuitive concept that tends to hold true in most situations (though there are exceptions).
