The resistors shown in the figure have the following values: R1= 80 ohms R2= 50 ohms R3= 130 ohms and R4= 200 ohms What is the equivalent resistance between points a and b? What is Req= the equivalent resistance between points band c? What is the equivalent resistance for the entire resistor arrangement (from a to c)? If a voltage difference deltaVac= 13volts is applied across the arrangement (from a to c), what is the total current flowing from a to c? What is the voltage difference between points a and b? What is the voltage difference between points b and c? How much current is flowing across resistor R3? How much current is flowing across resistor R4?

Consider an electric circuit below that consists of five resistors connected to a battery proving potential difference e =210 mV. The resistances of the resistors are: R1= 4.0 S, R2= 3.0 N, R3= 6.0 N, R4= 2.0 N, and R5= 5.O N.
