3 resistors of 3 Ω, 6 Ω and 8 Ω are in series with a 2V battery. Across which resistor is the potential difference minimum? |

Answer» the CONCEPT of OHMS Law is used. According to the ohm's law the current passing through a metallic element is DIRECTLY proportional to the potential difference across its and provided the temperature remains constant.✏️The total potential difference across the combination of resistor in series is equal to the SUM of potential difference across the individual resistor.✏️The current across each resistor remains the same in series arrangement.The total resistance in series arrangement is given by :-Now we will calculate the total resistance →Total voltage is given as 2 V✿According to ohm's Lawwhere v denotes voltageI denotes currentR denotes resistance→V= IR →V= 0.117× 6→V= 0.702 v→V= IR→V= 0.117 × 8→v=0.936 v______________________✷Verification---------------------------------------- |
