Question
For the circuit shown, identify, from choices (i) - (Iv), how each change described below will affect the current in the battery. This change will: increase the current in the battery. decrease the current in the battery. have no effect on the current in the battery. have an effect on the current in the battery that cannot be determined. All of these modifications are changes to the initial situation that is shown. The resistance in R, is reduced. Explain your reasoning. The resistance in R_i is reduced. Explain your reasoning. The resistance in R_1 and R_2 are increased by the same amount. Explain your reasoning. The resistance in R_1 is reduced, and in R_2 it is increased. Explain. Three resistors are connected to a battery as shown. Two points in the circuit are labeled A and B. Is the current at point A (i) greater than (ii) less than, or (iii) equal to the current at point B? Explain your reasoning.Explanation / Answer
Current in R1=V*R2/(R1+R2)
Current in R2=V*R1/(R1+R2)
Current in battery=V(R1+R2)/R1*R2
If R1 is reduced
Current will increase
If R2 is reduced
Current will increase
If R1 and R2 will increase by same amount
Current will decrease by same amount
If R1 is reduced and R2 is increase
Cannot be determined as we do not know R1 is less than R2 or opposite
