Answer:

I= 3.5 amps

Step-by-step explanation:

Step one:

given data

rating of resistor R= 8 ohms

power P= 100W

Required

The current I

Step two

Yet this power is also given by

P = I^2R

make I subject of the formula we have

$I= \sqrt{(P)/(R) }$

substitute

$I= \sqrt{(100)/(8) }\\\\I=√(12.5)\\\\I= 3.5 amps$
