Three resistors with values 1.1 , 3.4 , and 5.8 are connected in parallel in a circuit with a 6.4 battery.
What is the total equivalent resistance?
R = ohms

    It does not matter what the voltage is when computing the equivalent resistance, Req.

    1/Req = 1/R1 + 1/R2 + 1/R3

    Solve for Req. Compute 1/Req first and then take the reciprocal (one-over) of that. req = 1/(1/Req)
