Three 3.0 ohm resistors are connected in parallel. What is the equivalent resistance
The equivalent resistance of three 3.0 ohm resistors connected in parallel is 1.0 ohm.
When resistors are connected in parallel, the formula to calculate the equivalent resistance is given by:
1/Req = 1/R1 + 1/R2 + 1/R3 + ...
In this case, we have three 3.0 ohm resistors connected in parallel. To find the equivalent resistance, we substitute the values into the formula:
1/Req = 1/3.0 + 1/3.0 + 1/3.0
Simplifying the equation gives:
1/Req = 3/3.0
Now, we can find the reciprocal of both sides of the equation:
Req/1 = 3.0/3
Which simplifies to:
Req = 1.0 ohm
Therefore, the equivalent resistance of the three 3.0 ohm resistors connected in parallel is 1.0 ohm.
