उत्तर
To get total resistance more than 7Ω. We can connect 2Ω,3Ω and 5Ω in series.
1)
2)
`R_"equivalent"` = 2 + 3 + 5 = 10Ω

The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below:
| I (amperes) | 0.5 | 1.0 | 2.0 | 3.0 | 4.0 |
| V (volts) | 1.6 | 3.4 | 6.7 | 10.2 | 13.2 |
