# Formulas in physics electricity

Sep 07, 2018 · The three main equations representing the relationships between energy, work, and force. Work and energy in physics share a close relationship. According to the work-energy principle, an increase in a rigid body’s kinetic energy is caused by an equal amount of work done on that body by a force applied to that body.

May 15, 2018 · What Is the Formula for Energy? Force and Work. Newton's three laws of motion form the basis for classical physics. Kinetic and Potential Energy. An object in motion possesses its energy of movement,... Electrical Energy. The calculation of energy in electrical systems depends on the amount... ... Electricity: Ohm's Law. According to Ohm's Law electric potential difference(V is directly proportional to the product of the current(I times the resistance(R. V = I R. The relationship between power (P and current and voltage is. P = I V. Using the equations above we can also write. P = V 2 / R. and. P = I 2 R
The equation for kinetic energy is KE = 0.5 • m • v 2 where m is the mass of the object (with standard units of kilograms) and v is the speed of the object (with standard units of m/s). The total mechanical energy possessed by an object is the sum of its kinetic and potential energies.

Mar 06, 2018 · Energy is the most fundamental concept in physics. Whatever be the operating force (electromagnetic, gravitational, strong or weak), every change that occurs in the universe is a conversion from potential to kinetic energy.
In other words, assuming that the power from these formulas is the power used by a device is usually safe, but only when talking about steady state systems. The exception to this is when we're talking about the power source; in this case conservation of energy tells us that the power the charges acquire must come from the power source. Electricity Formulas are applied in calculating the unknown electrical parameters from the known in electric circuits. Example 1 Determine the current flowing through the electric heater have p.d of 220 V and resistance is 70 Ω. Solution: Given: Resistance R = 70 Ω. Voltage V = 220 V. The current formula is given by. I = V / R = 220 / 70 = 3.1428 A. Example 2 Static Electricity - the group of phenomenon caused by insulated objects becoming charged. Electrical Field - an area of space in which charged particles experience a force. Electric Field Lines - a representation of an electrical field with lines indicating the direction which a positively charged particle would move, i.e. from positive to ...
