The direct current (DC) power P (W) is determined by multiplying the applied voltage (U) by the current I (A), as shown above. In the example below, the amount of electrical energy determined by the previous equation is retrieved from the power supply and
Direct Current (DC) Power. Direct current, or DC, refers to power systems that use one polarity of voltage and current, however amplitude may vary (cyclic or random). Figure 2 - Basic circuit showing voltage and current with a DC voltage source. Ohm’s Law.
We can take all of the previous Ohm’s Law equations for finding Voltage, Current, Resistance and of course Power, and condense them into a simple Ohms Law pie chart for use in AC and DC circuits and calculations as shown.
13 wrz 2020 · Find out how power measurements in a dc circuit can be carried out with a voltmeter (V) & an ammeter (A) or directly with a Wattmeter.
DC power measurement is relatively simple as the equation is simply watts = volts x amps. For AC power measurement, the power factor (PF) introduces complexity as watts = volts x amps x PF. This measurement of AC power is referred to as active power, true power or real power.
