V-240 volts is the voltage imposed on all of the resistive loads. Formula I₁=V/R₁ L₂=V/R₂ 1₁=V/R₁ L-V/R₁ Is=V/Rs 16 V/R6 1=24 3. The unit of watts is a scalar quantity. Hence P= P.. Calculate 1, Amps 2. Before we can construct the circuit, we must first calculate the resistance of all loads, but these loads will be labeled with their rated watts on the circuit diagram. 4. Note that "I" can be calculated with Ohm's Law (I-V/R) or the Power Law, I = P/V. 5. Note also, that formula I-E1, represents Kirchhoff's Current Law. Calculation 6. It is sometimes necessary to first calculate the equivalent value of parallel resistances, as in LAB_S.
