In power transmission over long cables of resistance \( R_c \), if the power delivered at voltage \( V \) is \( P \), the wasted power \( P_c \) in transmission lines is proportional to:→Given below are two statements:\n Statement I: The potential difference across the terminals of a cell in a closed circuit is greater than its emf when it is being charged.\n Statement II: When a cell is being charged, current enters its positive terminal and the terminal voltage equation becomes \( V = \varepsilon + Ir \). \nIn the light of the above statements, choose the most appropriate answer from the options given below:→An electric toaster uses nichrome for its heating element. When connected to a \( 230 \text{ V} \) supply, the current settles at \( 2.68 \text{ A} \) at room temperature (\( 27.0^\circ\text{C} \)) with a resistance of \( 75.3\ \Omega \). When the steady temperature is reached, the current is \( 2.68 \text{ A} \) initially but if resistance rises, current changes.
