Problem: The battery in the figure below has negligible internal resistance.Find the current in each resistor.  1)A (3 Ω resistor)2)A (4 Ω resistor)3)A (vertical 2 Ω resistor)4) A (diagonal 2 Ω resistor)

FREE Expert Solution

Equivalent resistance for resistors in parallel:

1Req=1R1+1R2+...+1Rn

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

1)

R2, R3 and R4 are in parallel:

R234 = (1/R2 + 1/R3 + 1/R4)-1 = (1/2 + 1/2 + 1/4) = 0.8Ω

R1 and R234 are in series:
