So in this problem, we have a meter and with the government or inside. So the structure is like this, Uh, so we have two into resistant resistors are one or two and our wise from the Gavin Ah, meter. And our two in this problem as we're gonna read that our wives films aren't too is, uh, five times 10 to the negative Fifth sobs. All right. And a total Ah, total scale is Ah, I So the next invaluable eyes. Ah, three amperes. So if we reach this maximum current three amperes so we can see the current flowing to our one. So there's I won and I to so I want equal. I times are one parts are too. And the numerator where we are too. Okay, So this this video is we have the very for I and are one or two, so I can see that the videos of 15 my crime peers. So this is the sensitivity of the governor meter
