two resistors of resistance 6 ohm and 3 ohm are connected in series and then in parallel .calculate the equivalent series resistance and equivalent parallel resistance.

a. RT = 9 Ohms

b. RT = 0.5 Ohms

Explanation:

Let the two resistors be A and B.

Let RT be equivalent resistance.

Given the following data;

Resistor A = 6ohms

Resistor B = 3ohms

a. To find the equivalent series resistance;

RT = RA + RB

RT = 6 + 3

RT = 9 Ohms

b. To find the equivalent parallel resistance;

RT = 1/RA + 1/RB

Substituting into the equation, we have

RT = 1/6 + 1/3

RT = 3/6

RT = 0.5 Ohms
