Ohm’s Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points, and inversely proportional to the resistance (R) between them. Mathematically, this relationship is expressed as V=IR.
Yes, current is directly proportional to the potential difference. The current flowing through a conductor is proportional to the potential difference between its two ends. Mathematically, this can be expressed as I = V/R, where I is the current, V is the potential difference, and R is the resistance.
The current and intensity of light are directly related to each other. As the current increases, the intensity of the light increases proportionally. For example, when the current is doubled, the intensity of the light is also doubled. The intensity of light is a measure of the amount of energy the light produces, and this …
An ammeter is an instrument that measures electric current in a circuit. It is usually connected in series with the circuit so that all of the current passes through the ammeter. The ammeter then measures the electric current and displays the result as an electric current reading.
Electric current is the flow of electric charge through a material, usually a conductor such as a metal wire. It is measured in amperes (A). Electric current can be either direct current (DC) or alternating current (AC). DC flows in one direction, while AC periodically reverses direction.
Parallel connection is a type of connection used to link multiple devices together. It is a connection in which the data is transmitted simultaneously over a number of wires. It is most commonly used to connect printers and other external devices to a computer. Features of Parallel connection: • It is faster than the serial …

In a series connection, the components are connected one after the other in a single line. This means that the same current passes through each component and the total voltage across the circuit is the sum of the individual voltages. The main advantage of a series connection is that it is simple to wire and …
A combination of cells is a set of cells that are connected together in some way that results in a larger electrical system. This can include a number of different combinations, such as a series of cells connected in a circuit, a parallel connection of cells, or a combination of both. The combination of cells …

The electromotive force (emf) is a potential difference between two points in an electrical circuit, caused by an external power source, such as a battery or generator. It is measured in volts and is typically denoted by the symbol E or V.
