Question

the maximum current rating for a 10 kilo ohm 0.5 watt resistor is ?​

Answer 1

Explanation:

we know power(p)=I^2×R

here p =0.5 watt

and Risistance(R)=10kilo ohm =10000ohm

so,0.5=I^2×10000

so,I^2=5/100000

so,I=(1/100)(root1/root2)

Answer 2

Answer: 7.07mA

Explanation:

We know that the expression of power P= I^2R.

Now, I^2=P/R

=0.5/10000=5.0×10^-5

Hence the current I=√5×10^-5=0.00707

=7.07×10^-3

=7.07mA.
