calculate the equivalent resistance between the two points A and B in the following circuit diagram. |
| Answer» RESISTORS of 3Ω and 2Ω are also in series.∴ Their equivalent RESISTANCE, R 1 =3Ω+2ΩResistors of 6Ω and 4Ω are also in series.∴ Their equivalent resistance, R 2 =6Ω+4ΩNow, R 2 ,30Ω and R 2 are in parallel.Let R be the equivalent resistance.Then = R1 = R 1 1 + 301 + R 2 1 = 51 + 301 + 101 = 306+1+3 = 3010 orR= 1030 =3Ω Hence, the equivalent resistance between A and B is 3Ω. | |
