Physics Homework Solutions
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 ...continues
