Consider the above diagram 1) What is equivalent potential for batteries 1 and 2 if they are 4.0 Volts and 9 volts respectively. 2) If the resistors are R1: 3.9 ohms, R2: 6.1Ohms, and R3: 1.0 Ohms. and the batteries are the same, what is the current out of the batteries? 3) What is the voltage across V23 over R2 and R3?

Best ResponseYou've already chosen the best response.2The total potential is just the sum of the EMF's of the batteries (V1+V2). Resistors in series are added to find the total resistance. Kirchoff's law about the voltage changes of a closed circuit summing to zero then gives us\[V_1+V_2IR_{\text{total}}=V_1+V_2I(R_1+R_2+R_3)=0\]find the current by solving for I. The voltage change across a given segment is found from Ohm's law\[\Delta V=IR\]Where R is the total resistance across the segment. For example the change in voltage across resistors 1 and 2 would be\[\Delta V_{12}=I(R_1+R_2)\]
