Power In Circuit

You can easily calculate the Power of Load in circuit based on Current(I) and Load (R)parameters.This Circuit has a great significance in our daily life.You can also analyze the voltage and energy consumed in load.This circuit has solved in ideal conditions with ohms Law.Electrical Appliances use Power as a general parameter and we must know its relationship with voltage.So for this reason we hav solved a simplest for of load circuit in this app.This app is a fantastic education learning tool to learn voltage and power in terms of Volts and Watts.

When calculating the power dissipation of resistive components, use any one of the three power equations to derive the answer from values of voltage, current, and/or resistance pertaining to each component:

power equations

This is easily managed by adding another row to our familiar table of voltages, currents, and resistances:

voltage current resistance table

Power for any particular table column can be found by the appropriate Ohm’s Law equation (appropriate based on what figures are present for E, I, and R in that column).

An interesting rule for total power versus individual power is that it is additive for any configuration of the circuit: series, parallel, series/parallel, or otherwise. Power is a measure of the rate of work, and since power dissipated must equal the total power applied by the source(s) (as per the Law of Conservation of Energy in physics), circuit configuration has no effect on the mathematics.

REVIEW:

Power is additive in any configuration of resistive circuit: PTotal = P1 + P2 + . . . Pn
