Two circuits A and B are connected in parallel to a 12 V battery which has an internal resistance of 0.25 Ω. Circuit A consists of two resistors 1 Ω and 5 Ω connected in series. Circuit B consists of two resistors 4 Ω and 7 Ω connected in parallel. Calculate the currents flowing through and the voltages across each of the five resistors (the four resistors of circuits A and B and the internal resistance). Calculate the power dissipated...
Six 1.50 V batteries are connected in series, with the positive terminal of one battery connected to the negative terminal of the next. What is the emf of the combination? If the internal resistance of each battery is 2.00 Ω, find the terminal voltage when there is a current of 200 mA in the circuit.
Two AAA-size lithium batteries are connected in series in a flashlight. Each battery has 3.5 volt and 4- Amp-hour capacity. If the flashlight is connected to a light bulb with 10 Ohms resistance. How long does it take to drain the batteries?
An MP3 player takes two AAA batteries (1.5 V each) and has earbuds with a resistance of 60 Ω. Figure out the current used. A charged AAA battery has a capacity of 1000 mA hrs. For how many hours can you listen to music assuming you can totally drain the batteries? The batteries are in series to get 3 V.
A real battery is not just an emf. We can model a real 1.5 V battery as a 1.5 V emf in series with a resistor known as the "internal resistance", as shown in the figure(Figure 1) . A typical battery has 1.0 Ω internal resistance due to imperfections that limit current through the battery. When there's no current through the battery, and thus no voltage drop across the internal resistance, the potential difference between its terminals is 1.5 V,...

4) Many resistors are connected purely in parallel to a 17 battery and the power output of the battery is 172 Watts. One resistor is removed (but the rest remain connected in parallel to the same battery) and the current coming out of the battery is 3.1 amps with that resistor removed. What was the value of the resistance of the removed resistor in Ohms?
