You have developed a new way to measure the internal resistance of a battery. The circuit you have created is shown below, with a non-ideal battery (EMF and internal resistance r in the red box), a constant external resistor R1-19.122, and a variable resistor R2. R2 has a resistance you can change over a wide range of values, from nearly zero to nearly infinity. In this circuit, you measure the voltage over R2, AV2. R1 is used to avoid damaging...
10. In the circuit below, the battery has an emf, ε, of 1.5 V and an internal resistance, r, of 3.0 12. The resistance of R1 is 5.0 12, the resistance of R2 is 8.0 N and the resistance of R3 is 6.0 12. R2 w Ri R3 winti a) What is the voltage drop across R1? b) What is the terminal voltage of the battery? c) If another resistor is added to the circuit, parallel to R2, will the...
A circuit is constructed with five resistors and one real battery as shown above right. We model. The real battery as an ideal emf V = 12 V in series with an internal resistance r as shown above left. The values for the resistors are: R1 = R3 = 24Ω, R4 = R5 = 112 Ω and R2 = 126 Ω. The measured voltage across the terminals of the batery is Vbattery = 11.73 V.2) What is r, the internal...
PLEAASEE HELP!! A battery with an emf of 12.0 V shows a terminal voltage of 11.6 V when operating in a circuit with two lightbulbs, each rated at 4.0 W (at 12.0 V),which are connected in parallel. What is the battery's internal resistance?
Three resistors are connected to an ideal battery (no internal resistance) as shown. The values are: EMF = 19 V R1 = 39 Ohms R2 = 70 Ohms R3 = 66 Ohms What is the total power output by the battery? Hint: You might consider the current through each individual resistor.

Please help me answer this 3-part question based on the information that follows, showing work when helpful: a. What is the effective resistance of the resistors you used for number 3? b. Which of your measurements had the smallest relative uncertainty? c. Batteries have an internal resistance, which we have not considered in the lab. How would the internal resistance of your battery affected your calculations for part a? R1=10 KiloOhms, R2=2.2 KiloOhms, R3=1 KiloOhm, E1 and E2 each equal...
i need help with this page??? 1. (8 points total) A parallel plate capacitor whose plates have area A and plate separation d is connected to a battery. While the capacitor remiains connected to the battery, describe quantitatively what will happen to the charge on the capacitor if each if the following actions occur. That is, explain numerically how the magnitude of the charge on the capacitor in each circumstance compares to the original a. (3 pts) The distance between...
Batteries are not perfect. They can't deliver infinite current. As the current load on a battery gets larger, the voltage output gets smaller. We can represent this by treating batteries as if they have some small internal resistance. The circuit below shows a battery hooked up to a resistor, a voltmeter (for measuring voltages), and an ammeter (for measuring currents). When you put a measuring device on something, like a circuit, you don't want to change the circuit. So this...
