Question

Find the size of the resistor which would limit the current to a value of 2 mA when connected to an 8 V supply

Answer 1

R = 4000 ohms

Step-by-step explanation:

Given that,

Current, I = 2 mA

The voltage of the supply, V = 8 V

We need to find the resistance of the resistor. We know that, Ohm's law is as follows :

V = IR

Where

R is resistance

So,

`R=(V)/(I)\\\\R=(8)/(2* 10^(-3))\\\\\\R=4000\ \Omega`

So, the resistance of the resistor is 4000 ohms.
