l is the length of the conductor in meter (m)A is the cross sectional area of the conductor in square meters (m2) It is easy to understand this formula with water pipes analogy:when the pipe is longer, the length is bigger and the resistance will increase. when the pipe is wider, ...
Resistance of a conductor of length l and area of cross-section A is R. If its length is doubled and area of cross-section is halved, then find its new resistance. View Solution What happens to resistance of the conductor when area of cross section increases View Solution चालक...
To find the resistance of the conductor, we can use Ohm's Law, which states that: V=I×R Where:- V is the potential difference (voltage) across the conductor,- I is the current flowing through the conductor,- R is the resistance of the conductor. Given:- Current I=0.35A- Potential...
Conductivity, term applied to a variety of physical phenomena. In heat, conductivity is the quantity of heat passing per second through a slab of unit cross-sectional area when the temperature gradient between the two faces is unity. Electrical conductiv
The first law is represented by the statementR αL. This means, if the length of the conductor increases, the resistance also increases. In the same way, if the length of the conductor decreases, the resistance decreases. Second Law
Dynamic and static properties of the contact resistance of twisted conductor splices have been investigated. The splice resistance in a static condition increases (degraded) with time. This is described in terms of a probability density function in which the logarithm of the splice resistance is ...
The effect of temperature on the resistance of the conductor isdirectly proportional to each other. The increase in temperature of the conductor increases its resistance and makes it difficult to flow current through it. As discussed above, the movement of free electrons creates the flow of current...
The electrical resistivity (R) of a material is given by R = δL/A, where δ is the bulk resistivity in ohm-centimeters (Ω-cm), L is the length of the conductor in cm, and A is the cross-sectional area of the conductor in cm2. For a square of thin film of thickness, t, an...
Resistance is the obstruction offered to the flow of electrons when voltage is applied across the ends of the conductor. It is measured in the units of ohms. The resistance of a conductor depends on the physical structure of the conductor and the properties of...
