What type of quantity is capacitance?
Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791–1867). A farad is a large quantity of capacitance.
What makes a quantity scalar?
A quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude. For scalars, you only have to compare the magnitude.
Why work in physics is a scalar quantity?
Work is a scalar quantity because it is the dot product of two vectors (Force and displacement). Dot product of two vectors becomes scalar quantity. So, work done has only magnitude but not direction. Work done may be positive, negative or zero.
On what factors capacitance of a capacitor depends?
There are three factors which influence capacitance: the size of the conductors, the size of the gap between them, and the material between them (the dielectric). The bigger the conductors, the bigger the capacitance. The smaller the gap, the bigger the capacitance.
Why unit of capacitance is Farad?
The farad (symbol: F) is the SI derived unit of electrical capacitance, the ability of a body to store an electrical charge. It is named after the English physicist Michael Faraday (1791-1867)….

Why Microfarad is used as practical unit of capacitance of a capacitor instead of Farad?
Why is the capacitor unit always taken in a Microfarad? – Quora. Farad, defined by charge per unit volt, is considered too large a unit for practical use. Hence much smaller units of microfarad, picofarad, nanofarad, and even millifarad have been in use.
Is a scalar quantity *?
Scalar quantities have a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity.
Why Momentum is a vector quantity?
momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Thus, in the absence of a net external force acting on a collection of particles, their total momentum never changes; this is the meaning of the law of conservation of momentum.
