Your answer is partially correct. You are given a number of 43 Q resistors, each capable of dissipating only 2.0 W without being destroyed. What is the minimum number of such resistors that you need to combine in series or in parallel to make a 43 Q resistance that is capable of dissipating at least 7.1 W? Number i 9 Units No units

A galvanometer with an internal resistance of 7 ohms is connected in parallel to an unknown resistor R together with a shunt resistor of 4 ohms. A constant current I goes through and the galvanometer deflects to a certain amount. The resistor R is then taken away and repositioned in series with the galvanometer, leaving the shunt in parallel with this series combination. With the same current I, the galvanometer deflection remains the same. Calculate the value R of the unknown resistor R
