WebQuestion 2: Name a device that helps to maintain a potential difference across a conductor. Answer: Cell or battery. Question 3: Write relation between heat energy produced in a conductor when a potential difference V is applied across its terminals and a current I flows through for ‘t’. Answer: Heat produced, H = VIt. WebSolution 5. (a) Resistivity of iron = 10.0 x 10 -8 ohm m. Resistivity of mercury = 94.0 x 10 -8 ohm m. Resistivity of mercury is more than that of iron. This implies that iron is a better conductor than mercury. (b) It can be observed from the table that the resistivity of silver is the lowest among the listed materials.
WebApr 10, 2024 · We use power factor formula in electrical circuits. We can calculate the power with the help of the following formulas. 1st Electrical power formula: P = V × I. 2nd electrical power formula = P = I2R. If we combine both first and second electrical power formula, we get: P = V2R. The above formulas have: V = Application of a voltage across two ...
