Formula: $\rho = \frac{1}{\sigma}$ where: $(\rho)$ is the resistivity of the material in ohm-meters $(\Omega \cdot \text{m})$ , $(\sigma)$ is the conductivity of the material in siemens per meter (S/m). Current Current is the rate of flow of electric charge through a con...
The energy in motion is known as Kinetic Energy, whereas Potential Energy is the energy stored in an object and is measured by the amount of work done. Types of Energy Some other types of energy are given below: Mechanical energy Mechanical wave energy Chemical energy Electric energy Magnetic ...
work done time taken 20 000 = 50 = 400W Alternatively we could have calculated the speed first v= distance time 10 = = 0.2 m / s 50 and then calculated power Power = Force × Speed = Fv = 2000 × 0.2 = 400W Worked Example 3.7 A hoist operated by an electric motor ha of 500 ...

Tuning the surface dipole:This is done by changing the surface chemistry or structure of the material. Adding or removingatomsor molecules on the surface creates a dipole layer that modifies the electric field near the surface, affecting its work function accordingly. Changing the surface structure ...
Can the equation be used for electric power calculation?Yes, for electrical devices, power (P) can also be calculated as Voltage (V) multiplied by Current (I), aligning with (P=VI). What if the work is given in kilojoules (kJ)?Convert the work from kilojoules to joules by multiplying ...
Work done by Amir in 1 day = (1/3) – (7/24) = 1/24 Amount distributed between each of them = (1/6) : (1/8) : (1/24) = 4:3:1 Amount paid to Amir = (1/24) × 3 × 2400 = Rs.300 Q 3.Dev completed the school project in 20 days. How many days will Arun take...
it is very shocking that even though you feel fatigue but work done by you on the wall is zero. the displacement of the wall is zero. so according to the formula, \(\begin{array}{l}w = f.s\end{array} \) \(\begin{array}{l}w = f.0\end{array} \) \(\begin{array}{l}w ...
However, once again, he is adamant that F1 will not go all-electric. "We do not want to make technological wars against full electric mobility, as it is a technology that will have its own market." Meanwhile, F1’s chief technical officer, Pat Symonds believes that part of the reason ...
