Hello All,
Im self studying Electronics at home, and I at the moment on Ohms Law.
Now I have a problem:
"What is the increase in current when 15v is applied to 10,000 ohm rheostat, which is adjusted to 1000 ohm value?"
Now I have worked out that the power through the Rheostat is:
a. 0.015A at 1000 ohms, and
b. 0.0015A at 10,000 ohms.
But Im stuck on the power increase. It looks like ten percent, but I could be wrong.
Any clues?
Cheers
Glenn.
