Consider the following diagram of a parallel circuit.


Δ\displaystyle \Delta Vtot  = 31

R1 = 15

R2 = 12

R3 = 16

Using the information above, determine the total (equivalent) resistance, total current from battery, current through each resistor, and voltage drop across each resistor.

V1 = V

V2 = V

V3 = V

I1 = A

I2 = A

I3 = A

Itot = A

Req =  Ω\displaystyle \Omega
