Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).

How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
How do you calculate electrical power?
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is the relationship between voltage power and 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
Can electrical power be calculated by multiplying electrical pressure by current?
If you are defining electrical pressure as voltage then the answer to your question is yes. W = A x V.
How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
How can you calculate the current an appliance can use?
current=watts(power)/voltage
HOW CAN you calculate power if you know the voltage and current?
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.
How do we calculate voltage?
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
How do you calculate power loss from a resistor?
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.
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
How do we calculate?
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
When voltage increases what happens to the amps?
the power will also increase as it is proved in my experiment
How do you calculate electrical power?
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
How do you calculate DC power if voltage and currents are given?
P = E * I Power (watts) equals voltage (E) times current (I)
What is the formula of load calculation?
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.
How do you calculate absorbed power for motors?
we can calculate power consumption of motor by multiplying voltage and current which motor is take.AnswerYou need to know its rated power (i.e. its output power) and its full-load efficiency, from which you can calculate its input power.
