I had a problem in physics but I never learned anything about it in highschool.We passed this lesson with no idea what a rheostat does or is.
Can someone explain me?I hope that you learned this during your training as an electrician because I never learned that.
Well if I still have the problem I will show you the details:
E=15v,r=5 ohms,R(AB)=40 ohms,Resistor of Ampmeter is 0.
Calculate:
a)ampmeter indication when the cursor C is in the position B
b)rheostat voltage between points A and M when the cursor C is on the position M
c)voltage of every battery supply(E,r) when cursor C is on the position M
d)indication of the ampmeter when one of the batteries is polarized inverse.
I have no idea how to solve this.Can someone explain to me by solving this problem?
