Answer 2

Answer:

Explanation:Voltage across each resistor is same and equal to the applied voltage.

→ Total current is equal to sum of currents through the individual reistances.

• I = I1 + I2 + I3

⇒ V/R = V/R1 + V/R2 + V/R3

→ Reciprocal of equivalent resistance is equal to sum of reciprocals of individual resistances.

1/Rp = 1/R1 + 1/R2 + 1/R3

→ Equivalent resistance is less than the value of the smallest individual resistance in the combination.
