Answer» Solution :Given:Power input (P) = 1000 W, Potential difference (V) = 250 V To find : Electric CURRENT (I) and Resistance (R) Formula : P = VI and V = IR Solution :We know that powerP=VI `therefore` 1000 W = 250 V x I `therefore I="1000 V"/"250 V"=4 A` We know, resistance R = V /I `therefore R="250 V"/"4A"=62.5 Omega`
