Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
Yes, in direct current (DC) circuits where the voltage and current are in phase, voltamps (VA) are equal to watts (W). However, in alternating current (AC) circuits where the voltage and current may not be in phase, the relationship between voltamps and watts can vary depending on the power factor of the load.
In a Direct Current circuit power is equal to the product of current times voltage or in another form of the same equation, power divided by voltage equals current in amps. 280 watts divided by 24 volts equals 11.6666666 amps.
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.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
(watts equal) voltage times current (e x I ) 120 x 20 resistance times current squared (r x I squared) 6 ohms x20 squared voltage squared divided by resistance (E squared divided by resistance) 120squared divided by 6 check OHMS LAW,
Volts time amps equals watts so watts divided by volts equal amps.
Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)
Power, in 'watts'.
W=V x A Watts equal volts times amps.Current = voltage divided by resistance

The current flowing through a bulb is equal to the (voltage across the bulb) divided by the (bulb resistance), and can be expressed in Amperes. The rate at which the bulb dissipates energy is equal to (voltage across the bulb) times (current through the bulb), and can be expressed in watts.
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
Yes, electrical power in Watts is volts x amps
Watts equal volts times amps, which is 40 x 0.5 or 20 watts.
For DC, the power (in watts) is equal to the current (in amperes) multiplied by the voltage (in volts). For AC, you also need to multiply a so-called "power factor", but in practice, this is often close to 1.
