On this question, we're given the information of a truck battery, which is 12 volts, and we know that it's rated at 180 amp hour.
00:14
Voltage is 12 volts, and then the rating of the battery is 180.
00:31
We have to find out how much charge can be pumped into the battery.
00:36
For that, we're going to use the equation i for current.
00:41
Is q over t.
00:44
We're trying to find out the charge.
00:49
So we need to rearrange the equation.
00:52
Q is i delta t.
00:57
If we look at this, we can find out that those are the units for this.
01:12
Hours, two seconds.
01:17
So we do 180 times 60 minutes in one hour times 60 seconds in one minute.
01:33
Times 60 seconds in one minute.
01:37
When we solve for that, we get 6 .480.
01:45
4 a times 10 to the fifth cool arms...
