How is Voltage related to Resistance?

The relationship between voltage and resistance is represented by Ohm's Law. It usually means that the flowing current passing via a circuit is directly proportional to the applied voltage and also inversely proportional to the resistance, with a condition that the temperature remains constant.

The relation between voltage and resistance can be expressed as:

Voltage

Voltage is also referred to as Potential Difference.
Potential Difference can be expressed as the work done in obtaining a unit positive charge from one point to another point in the same conductor.
Volt (V) is the unit of potential difference.

Resistance

When current passes or flows through a circuit, it undergoes a given resistive force.
The parameter that usually represents the magnitude of this resistive force is often called resistance.
Ohm (Ω) is the unit of resistance.

What is Ohm's Law?

As per Ohm’s Law, the current that flows through a circuit is directly proportional to the voltage. Assume that:

V = Voltage
I = Current
R = Constant of Proportionality

Therefore,

V∝I

or, V = IR

Thus, this is how the relation between voltage and resistance can be expressed.

Read the following paragraph and answer the questions that follow.
A p-type or n-type semiconductor can be converted into a p-n junction by doping it with suitable impurity. The motion of majority charge carriers causes diffusion current across the junction while the barrier electric field causes motion of minority carriers for drift current. In case of unbiased diode, the diffusion and drift currents are equal. This equilibrium is disturbed by the biasing batteries. Diodes, therefore, allow currents in one direction. This property of diode is used in making rectifiers.

An astronomical telescope consists of two converging lenses. One of them of large aperture and large focal length is called objective lens and the other one, of smaller focal length and smaller aperture is called the eyepiece. It is used to see distant objects which are not seen clearly with naked eyes. The image formed by the objective lens acts as an object for the eyepiece and the final image produced by the eyepiece is magnified.

Capacitors are manufactured with certain standard capacitances and working voltages. However, these standard values may not be the ones that are actually needed in a particular application. Two or more capacitors can be grouped in series or in parallel to achieve desired capacitance and voltage. When connected in series, the total capacitance decreases while the voltage rating increases, whereas in parallel connections, the total capacitance increases and maintains the same voltage rating. A capacitor stores energy in the electric field between its plates and stored energy is proportional to the square of the voltage and capacitance $U = \frac{1}{2}CV^2$, where symbols have their usual meanings.
Two capacitors, one of $3 \ \mu$F and the other of $6 \ \mu$F, are connected in series in the circuit as shown in the figure, for a long time. }

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.
