Question

On a box are the words 12 Volt : 50 mA
What is the resistor in Kilo-Ohm?

Answer 1

R = 0.24 kilo-ohm

Step-by-step explanation:

Given that,

Voltage, V = 12 volt

Current, I = 50 mA = 0.05 A

We need to find the resistance of the resistor. We can find it using Ohm's law. So,

V = IR

`R=(V)/(I)\\\\R=(12)/(0.05)\\\\R=240\ \Omega`

or

R = 0.24 kohm

So, the value of resistance is 0.24 kilo-ohm.
