WebGood to know: I = Current in Amperes (A) V = Voltage in Volts (V) P = Power in Watts (W) R = Resistance in Ohm (Ω) Z = impedance = Resistance of AC Circuits in Ohms. Cosθ = Power factor = Phase … WebThis means that for every extra joule that is transferred per second, the power increases by one watt. Example Two electric motors are used to lift a 2 N weight through a vertical height of 10 m.
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. WebHowever, these power equations are so commonly associated with the Ohm’s Law equations relating voltage, current, and resistance (E=IR ; I=E/R ; and R=E/I) that they are frequently credited to Ohm.
