square root The relationship between the resistance R, power P and the voltage u at both ends of an electrical appliance is p = u & # 178; △ R. the resistance of an electrical appliance is 15 Ω. Now the power of this electrical appliance is 1500 W. please help to calculate how much voltage the electrical appliance should be connected to?
