Answer» Given: A heating element is MARKED 210V,630WTo find the resistance of the element when connected to a 210V dc source.Solution: The power of the heating element is 630 Watt and its voltage is 210V. Thus, the current drawn can be calculated with the formula P=VI, where P denotes the power, V stands for the voltage and I is the symbol of the current. So the VALUE of the current drawn = VP = 210630 =3AAnd the resistance of the element when connected to a 210V dc source = IV = 3210 =70Ω |
