Question

if the three resistors 2 ohms and 4 ohms are connected in series than the effective resistance in the circuit will be ............​

Answer 1

Explanation:

If three resistors 2 ohm, 3 ohm and 4 ohm are connected in series, then effective resistance in a circuit will be ohm.

Answer 2

• From the question, the correct answer is 9.

• As we know that there are three resistors $2ohms, 3ohms, 4ohms.$

• They are connected in series.

• Then let find the effective resistance in the circuit.

                         $R = R1+R2+R3$

                             $= 2+3+4$

                             $=9$

• Hence, the effective resistance in the circuit will be $9$.
