Answer: Remember the formula V = IR ?
That’s all you need.
You know the current through the resistor, and you can easily work out the voltage drop required across the resistor, so it’s a bit of simple arithmetic to work out the value of R required.
Now do your own homework
Explanation:
Answer:
280 ohms
Explanation:
I = V/R
Then you make R the subject of the formula
R = V/I
R = 28/0.1
R= 280 ohms
