- Part (b): Watts, volts, and ohms are SI units that can be expressed in the 'base' SI units as follows: kg-m² 53 ohm = kg-m² $³.A21 watt = volt= bottle cm kg.m² $3.A' (Recall that 'A' is the abbreviation for an ampere.) Use algebra and the equation at the top of the page (P=V²/R) to show that the base SI units for watts equal the base SI units for volts²/ohms. You do not need any numbers in this algebraic exercise. Instead, treat each of the base SI units (kg, m, s, A) as if it were an algebra variable (like x or y). Start with the following equation and substitute the base SI units for watt, volt, and ohm: watt = volt² ohmSolve the following problems. identify the given, the unknown, give the formula to be used, show the solution, and express the final answer into 2 decimal places.
