Yes. I = P/E which says current (I) equals power (P) divided by voltage (E). We normally see PIE, which is P=I x E or power equals current times voltage. If we divide both sides by E, we'll isolate I and express it in terms of P and E, as shown. The "PIE" thing is a nemonic (memory aid) to help you recall the formula.
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
That is the basic one. P=I*E. Power in watts (P) equals current flow in amps (I) times the potential voltage (E) in volts.
Power = Current * Voltage * Power FactorAbove expression can further be explore as :1. For DC CircuitsPower = Current * Voltage2. For Single Phase AC CircuitPower = Current * Voltage * Power Factor3. For Three Phase AC CircuitPower = Line Current * Line Voltage * Power Factor

Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
Power consumed by the appliance = (DC supply voltage) x (DC current)
Voltage x current = power (watts)
You get power, which is voltage * current (so both!).
P = I^2 R = IV = v^2 / R , Where P is power, I is current, R is resistance, and V is voltage. Given voltage and current, power = current * voltage, or P = IV.
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
If the resistance is 1.2k and the current is 0.024 ma, then the voltage is 0.0288 volts. (Voltage = resistance times current) If the voltage is 0.0288V and the current is 0.024 ma, then the power is 0.6912 microwatts. (Power = voltage times current)
