Question

Can someone help me please? I’ve been trying to solve these questions all day.

Answer 1

#16

If we put a resistor in circuit it will slow the speed of current

Let's check ohms law

`\\ \rm\Rrightarrow (V)/(I)=R`

• So if resistance is more current is less

#17

Again use ohms law

`\\ \rm\Rrightarrow V=IR`

`\\ \rm\Rrightarrow V\propto I`

• Voltage must be increased
