4.5 points A student in the laboratory connects a R1- 60 0 resistor, and a R2 = 25 0 resistor in series and then connects the arrangement to a 240-V dc source. (a). Calculate the total resistance in the circuit. (1.5 points) W R1 R2 AV (b). How much current is in the circuit? (1.5 points) (c). What is the voltage across the R2 - 25 0 resistor?
