A 16.0 ohm and a 24.0 ohm resistor are connected in parallel. A difference in potential of 32.0 V is applied to the combination.
What is the equivalent resistance of the parallel circuit?
What is the total current in the circuit?

Compute the equivalent resistance R with the equation
1/R = 1/R1 + 1/R2,
which can be rearranged to give
R = R1 R2/(R1 + R2)
I = V/R (use the equivalent R)
