WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy.
WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into the equation for electric power to obtain. P = I V = ( V R) V = V 2 R. This gives the power in terms of only the voltage and the resistance. banese internet banking baixarbanese gumersindo bessaWebWithin this booklet, you will find electrical load information, plus an outline of generator surge capability, fuel pipe sizing, liquid propane tank sizing, and UPS/generator compatibility.
