Answer:
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
