An electric iron has a rating of 750 watt and 220v calcuate the current and resistance |
|
Answer» Given : 750 P,220 V To find : CURRENT (I)and Resistence (R) Sol: P = V² ÷ R 750 = 220 x 220 ÷ R 750÷220 = 220 ÷ R 3.4090 = 220 ÷ R 3.4090 x 220 = R 749.98 = R Therefore, R = 749.98Ω. P = V x I 750 = 220 x I 750÷220 = I 3.4090 = I Therefore, I is 3.4090 A. if you are SATISFY with my ans then mark me as a brainlist if there is something wrong then kindly rectify it. |
