Calculate the equivalent resistance of the circuit below.
(5%)

4.7 ohms

Explanation:

Resistors 2 ohms and 5ohms

are parallel to each other ,so, their net resistance

= 1/2 + 1/5

LCM of 2 and 5 = 10

Divide the LCM by the Denominators of both fractions and multiply the results by the numerators. Also, the LCM becomes the denominator of the results

We have 5 + 2 /10

7/10 = 0.7 ohms

0.7 ohm is now in series with 4 ohms

Therefore 4 ohms + 0.7ohms

= 4.7 ohms

Therefore, the equivalent resistance of the circuit is 4.7ohms

where is the circuit diagram ?
