Equivalent resistance for 2 resistors in parallel:

Req=R1R2R1+R2

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Ohm's law:

V=iR

Resistors c and d are in series:

Rcd = R1 + R2 = 5 + 5 = 10Ω

Resistor b is in parallel with resistors Rcd:

Rbcd = (R1R2)/(R1 + R2) = (10 × 10)/(10 + 10) = 5Ω

Resistor a is in series Rbcd:

Req = R1 + R2 = 5 + 5 = 10Ω
