#16
If we put a resistor in circuit it will slow the speed of current
Let's check ohms law
[tex]\\ \rm\Rrightarrow \dfrac{V}{I}=R[/tex]
- So if resistance is more current is less
#17
Again use ohms law
[tex]\\ \rm\Rrightarrow V=IR[/tex]
[tex]\\ \rm\Rrightarrow V\propto I[/tex]
- Voltage must be increased
