A circuit contains two 90 Ω resistors connected in parallel. What's the total circuit resistance?

Total circuit resistance = 45ohms

Explanation:

Given that R1 = 90 and R2 = 90

Rt = total circuit resistance

Resistance in parallel:

Resistance in parallel is found by:

1/Rt = 1/R1 + 1/R2

1/Rt = 1/90 + 1/90

Take the L. C. M and simply

1/Rt = (1 + 1) / 90

1/Rt = 2 / 90

1/Rt = 1/45

Rt = 45 ohms

Total circuit resistance = 45ohms
