In the circuit shown in the figure both batteries have insignificant internal resistance and the idealized ammeter reads 1.50 A in the direction shown. What is the emf V of the battery and is the polarity in the correct direction?

A carbon wire and a nichrome wire
A carbon wire and a nichrome wire are connected one after the other. If the combination has total resistance of 11.0 k ohms at 20° C, what is the resistance of each wire at 20° C so that the resistance of the combination does not change with temperature? It seems as though resistivity may need to be considered in order for this problem to be solved. Can anyone help me here?
