Since power and voltage is given, we use P=IV to solve for the current I, correct ? And thanks!gneill said:Hi pandamonium, Welcome to Physics Forums.
Can you determine the amount of current drawn by the lights?
That's right. What value do you get for the current?pandamonium said:Since power and voltage is given, we use P=IV to solve for the current I, correct ? And thanks!
I got I=10.gneill said:That's right. What value do you get for the current?
Okay, now take a closer look at the units of the battery capacity. How long will you have to draw 10 A to equal that capacity?pandamonium said:I got I=10.
Oh, since 95 is the total charge that the battery can produce before failing, I can divide 95/10 to get the time before it fails, correct ?gneill said:Okay, now take a closer look at the units of the battery capacity. How long will you have to draw 10 A to equal that capacity?
Yes. You can check your logic by working with the units.pandamonium said:Oh, since 95 is the total charge that the battery can produce before failing, I can divide 95/10 to get the time before it fails, correct ?
Thanks for all the help ! I really appreciate it c:gneill said:Yes. You can check your logic by working with the units.
The charge in a batter can be measured in units of coulombs, which is a measure of electric charge.
The rate at which a batter loses its charge can be affected by factors such as temperature, the type of material used in the battery, and the amount of usage or discharge cycles the battery has gone through.
Yes, the type of battery can affect how long it takes for it to lose its charge. For example, lithium-ion batteries tend to hold a charge longer than lead-acid batteries.
Yes, a battery can lose its charge even when it is not being used. This is known as self-discharge and can occur due to internal chemical reactions within the battery.
Yes, there are ways to extend the lifespan of a battery's charge. Some tips include avoiding extreme temperatures, avoiding overcharging or completely draining the battery, and using the battery regularly rather than letting it sit for long periods of time.
