Explore In the animation, the two resistors are connected directly to the battery, so they both share a portion of the battery voltage Resistors connected in series may be replaced by an equivalent resistor given by the following equation R﹃ = Ri + R2 + R3 + (2) Circuit elements connected in series always have the same current. 1-12-1(3) Click to enable Adobe Flash Player Display in a New Window Display in a New Window Exercise 28.AF.4 Find the equivalent resistance, current, and voltage across each resistor when the specified resistors are connected across a 2 V battery. Part (a) uses two resistors with resistance values that can be set with the animation sliders, and you can use the animation to verify your calculation. In Part ·hee resistors are specified (a) Two resistors are connected in series across a 2 V battery, as illustrated above. Let R1-5 Ω and R2-3 Ω. Reg- Your response differs from the correct answer by more than 100% (b) Add a third series resistor to the circuit (you cannot do this with the animation-just calculate the result). Let R1 = 5 Ω,R2 = 3 Ω, and R3-4 Ω. avr = Summary As R 1 increases, the total current-Selact s R1 increases the potential difference across R1 Select As R1 increases the potential difference across R2 -Select-
