Can someone help plz!!

v=2

Step-by-step explanation:

180-104=76

76=18v+20v

76/38=v

v=2

18v and 104v

Step-by-step explanation:

In an 18V/20V Max system, they are always set in groups of 5 wired in a series. Each group of 5 is then wired in parallel to increase the number of amp hours and overall battery capacity in watt-hours. For more on that, check out our feature on Voltage vs. Amp Hours. Each one of those battery cells has two voltage ratings – nominal and maximum.

There are incremental gains with each step up in voltage in terms of power, battery run time, technological staying power. 20 and 18 V systems are the same, it's just the way Dewalt and Porter Cable initially distinguished between 18V nicad systems and lithium ion systems. 24V is probably different, but I haven't looked into Kobalt's system.
