Chapter 22, Problem 51GP
The total charge a battery can supply is rated in mA · h, the product of the current (in mA) and the time (in h) that the battery can provide this current. A battery rated at 1000 mA · h can supply a current of 1000 mA for 1.0 h, 500 mA current for 2.0 h, and so on. A typical AA rechargeable battery has a voltage of 1.2 V and a rating of 1800 mA · h. For how long could this battery drive current through a long, thin wire of resistance 22 Ω?

- You have a circuit with a battery hooked up to 2 capacitors in Parallel. The battery has a voltage of 4.3 V. The capacitors have a value of C1 = 40.0 µF and C2 = 25.0 u F. While finding the actual voltage is very helpful, it's hard to use this as a prediction because not all batteries are the same. So one way to look at this is a percentage. Even if the voltage of the battery is different, the percentage of the voltage should be the same regardless. Find the percentage of the battery voltage that is across capacitor 1. To find percentages: • Find the voltage across the specific capacitor just like previously Divide this voltage by the voltage of the battery • Multiply your answer by 100 to turn it into a percent Your answer should include: 2 Decimal Places Correct SI Units Your Answer:arrow_forwardA battery provides a voltage of 10.0 V and has unknown internal resistance Rnt.
