Google 'Ohms Law'
AnswerOhm's Law has nothing whatsoever to do with power.
The fundamental equation for power in a d.c. system is: P = E I (where P = power, E = supply voltage, and I = load current). From this equation, two others can be derived: P = I2R and P = E2/R, where R = resistance.
For a.c. systems, the fundamental equation must be multiplied by the load's power factor (cosine of the phase angle).

What is the relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit, as represented by the equation Pi2r?
The relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit is represented by the equation Pi2r. This equation shows that power dissipation is directly proportional to the square of the current and the resistance in the circuit.
What is the equation for energy transferred by an electrical appliance?
The equation for energy transferred by an electrical appliance is given by the formula: Energy (E) = Power (P) x Time (t). In this equation, Power is measured in watts (W) and Time is measured in seconds (s) or hours (h). This formula is derived from the definition of power as the rate at which energy is transferred or converted.
Which equation is used to calculate the amount of electrical energy used?
The equation used to calculate the amount of electrical energy used is: Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours).
What is the relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit, as represented by the equation P i2r?
The relationship between power dissipation (P), current (i), and resistance (r) in an electrical circuit is represented by the equation P i2r. This equation shows that power dissipation is directly proportional to the square of the current and the resistance in the circuit.
What is the relationship between power, current, and voltage in an electrical circuit?
In an electrical circuit, power is the product of current (the flow of electric charge) and voltage (the force that drives the current). The relationship between power, current, and voltage is described by the equation P I x V, where P is power, I is current, and V is voltage. This equation shows that power increases when either current or voltage increases in a circuit.
What is electrical fore proportional to?
In a direct current (DC) circuit, electrical power is proportional to both voltage and current according to the equation P = V * I, where P is power, V is voltage, and I is current. This relationship dictates that as either voltage or current increases, electrical power will also increase.
What is a equation for electric energy?
electrical energy (in kWh) = electric power (in kWh) X time (in hours) E=Pt
What equation is used to calculate the amount of electrical energy used?
The equation used to calculate electrical energy is E = P x t, where E is the energy consumed in kilowatt-hours (kWh), P is the power in kilowatts (kW), and t is the time in hours.
What is the chemical equation for power?
Power hasn't a chemical equation.
What is the equation for wattage?
Wattage = voltage times amperage. That's for DC. For AC there is a power factor PF = cos phi you have do multiply with.AnswerThe above answer suggests that power ('wattage') is an electrical unit, which it is not. In fact, power is defined as the rate of doing work, so the basic equation is work divided by time.
What Electrical motors convert what power to what power to power?
Electrical motors convert electrical energy into mechanical energy.
