three resistances of 12 ohms are connected in parallel what is the equivalent resistance
Answers
Explanation:
For the total resistance when the resistors are in parallel to each other, we use:
1
R
T
=
1
R
1
+
1
R
2
+
...
+
1
R
n
The situation you describe seems to be this:

So there are 3 resistors, meaning we will use:
1
R
T
=
1
R
1
+
1
R
2
+
1
R
3
All resistors have a resistance of
12
Ω
:
1
R
T
=
1
12
+
1
12
+
1
12
Total up the Right Hand Side:
1
R
T
=
3
12
At this point you cross multiply :
3
R
T
=
12
Then simply solve it:
R
T
=
12
3
R
T
=
4
Ω
