Q4. The electric current I (in amperes) and the appliance uses is given by,  I=√P/R where P is the power (in watts) and R, is the resistance (in ohms). Estimate the current an appliance uses when the power is 150 watts and the resistance is 8 ohms. Round to the nearest tenth.

GPT-5 mini · Answer

I = √(P/R) = √(150/8) = √18.75 ≈ 4.3301... So the current is about 4.3 A (to the nearest tenth).
