Question

Ohm’s law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.

Answer 1

The current is proportional to the voltage and inversely proportional to the resistance. This mean if the resistance decreased and the voltage stayed constant, the current will increase.

Step-by-step explanation:

Let's star with a closed circuit with a constant voltage of 48V, and a variable resistor selector of 6, 4 and 2 Ohms.

Using Ohm's Law equation
`I=(V)/(R)`

With the variable resistor selector on 6 Ohms

`I=(48V)/(6ohms) =8A`

Changing the selector to a 4 Ohms

`I=(48V)/(4ohms) = 12A`

Last, changing the selector to a 2 Ohms

`I=(48V)/(2ohms) =24A`
