Answer» Answer: The answer to this question is (a) 48 ohm (b) 2 ohm Explanation: The highest RESISTANCE is = R = R1 + R2 + R3 + R4 R = 4 + 8 + 12 + 24 R = 48 ohm The longest Resistance is = 1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 1/R = 1/4 + 1/8 + 1/12 + 1/24 1/R = 1/2 R = 2 ohm. Therefore The LOWEST resistance = 2 ohm. I HOPE IT WILL HELP YOU. |
