Answer» tion:Answer: The TOTAL resistance of a circuit CONNECTED to the given cell of emf 15 V is the SUM of all the resistances from various sources like, resistors, ammeter, voltmeter, ETC., connected in SERIES along with the internal resistance of the cell. ... Therefore, V=15V−(1.25×3)=11.25V. |
