V over R, or V/R, stands for voltage divided by resistance. Voltage is the measure of electrical potential energy between two points in a circuit, and is typically measured in volts (V). Resistance, on the other hand, is the measure of how much a material or component resists the flow of electrical current, and is typically measured in ohms (Ω).
When a voltage is applied to a circuit, the resulting current flow can be determined by dividing the voltage by the resistance. This formula, known as Ohm’s Law, is expressed as I = V/R, where I is the current in amperes (A).
V/R is a crucial calculation in electrical engineering, as it allows engineers to determine the current flow through a circuit and ensure that it is operating within safe parameters. For example, if the voltage applied to a circuit is too high, the current flow may exceed the capacity of the components in the circuit, causing them to overheat and potentially fail.
By calculating V/R, engineers can ensure that the current flow is appropriate for the components used in the circuit.
In addition to its practical applications, V/R is also used conceptually in physics to describe the relationship between electrical potential energy and resistance. A greater voltage applied to a circuit with a higher resistance will result in a smaller current flow, as more energy is required to overcome the resistance.
V/R is an important calculation in electrical engineering that determines the current flow through a circuit, and is also used conceptually to describe the relationship between voltage and resistance in the context of electrical potential energy.

How do you prove something is a vector space over R?
To prove that something is a vector space over R, we need to show that it satisfies the axioms of a vector space.
First, we need to establish what “something” refers to. It could be a set, a subspace or a quotient space. For simplicity, let’s assume that “something” refers to a set of vectors.
To begin, we need to show that the set has a well-defined addition operation. This means that for any two vectors u and v in the set, we can add them together to get a unique vector w, also in the set. We must also show that this addition operation is commutative (u + v = v + u), associative ((u + v) + w = u + (v + w)), and that there exists a zero vector 0 such that u + 0 = u for all vectors u in the set.
Next, we need to show that the set is closed under scalar multiplication. This means that if a is any scalar in R, and u is any vector in the set, then the product au is also in the set. We must also show that scalar multiplication is distributive (a(u + v) = au + av), and that it’s compatible with field multiplication (a(bu) = (ab)u) and identity (1u = u).
Furthermore, we need to show that the addition and scalar multiplication operations satisfy additional properties. Specifically, the set must satisfy the following:
– For any vector u in the set, there exists an additive inverse -u such that u + (-u) = 0.
– The distributive property a(u + v) = au + av also holds in reverse, that is, (a+b)u = au + bu.
– Finally, the scalars must form a field, that is, they must satisfy the usual axioms of addition and multiplication, as well as the existence of an additive identity, additive inverses, and the multiplicative inverse for all non-zero scalars.
These properties may seem like a lot to prove, but in most cases, many of them will follow naturally from the definition of the set or subspace. For example, a subspace of R^n will automatically be closed under addition and scalar multiplication, so we only need to confirm that it satisfies the other axioms.
To prove that something is a vector space over R, we need to show that it satisfies the axioms of a vector space, which outline the properties of addition and scalar multiplication operations. The specific steps involved in proving this will depend on the particular set, subspace, or quotient space we are dealing with.
