How Does Battery Size Affect Charge Transfer in a Flashlight?

In summary, a 1.5-volt, AAA cell and a 1.5-volt, C cell both supply 750 milliamperes of current through a flashlight bulb, with the AAA cell supplying 750 milliamperes for 5.0 minutes and the C cell supplying 750 milliamperes for 20 minutes. The total charge transferred by the C cell through the bulb is four times as great as the total charge transferred by the AAA cell. The equation W=VIt relates charge, current, and time, and the definition of current is I=\frac{dQ}{dt}.

Homework Statement


A 1.5-volt, AAA cell supplies 750 milliamperes
of current through a flashlight bulb for 5.0 minutes,
while a 1.5-volt, C cell supplies 750 milliamperes
of current through the same flashlight
bulb for 20. minutes. Compared to the total
charge transferred by the AAA cell through the
bulb, the total charge transferred by the C cell
through the bulb is
(1) half as great (3) the same
(2) twice as great (4) four times as great

What equation relates charge, current, and time?
 
  • #3


The definition of current is [tex]I=\frac{dQ}{dt}[/tex]. What is a formilar?
 

1. What is the definition of total charge transferred?

Total charge transferred is a measure of the total amount of electric charge that has moved from one point to another in an electrical circuit or system.

2. How is total charge transferred calculated?

Total charge transferred can be calculated by multiplying the current (in amperes) by the time (in seconds) that the current has been flowing.

3. Why is it important to measure total charge transferred?

Measuring total charge transferred is important because it helps to understand the amount of electricity being used in a circuit or system, which is essential for monitoring energy usage and ensuring the proper functioning of electrical devices.

4. What is the unit of measurement for total charge transferred?

The unit of measurement for total charge transferred is the Coulomb (C). 1 Coulomb is equivalent to the amount of charge transferred by a current of 1 ampere in 1 second.

5. How does total charge transferred relate to voltage and current?

Total charge transferred is directly proportional to both voltage and current. This means that as voltage or current increases, the total charge transferred will also increase. Similarly, decreasing voltage or current will result in a decrease in total charge transferred.
