Volts are an electrical measure of potential difference and Watts are a measure of power.
The high school physics way of calculating the power (P) in watts, would be to multiply the given current (I) by the voltage (v).
P = V * I
From Ohms Law we know that V = I * R,
where R is the resistance of the electrical circuit given in Ohms, so we could also state that
P = (I * R) * I = I2 * R
So you have two equations there that should be useful.
Yes, you can plug in a 12 volt pump to a 400 watt inverter as long as the pump's power requirements do not exceed 400 watts. Make sure the inverter is designed to convert 12 volts DC to 120 volts AC to power the pump effectively.
If the voltage supplied to the lamps is its operating voltage both lamps will have relatively the same output in brightness. If the 60 watt 110 volt lamp is used on a 220 volt supply, it will glow very brightly and then the lamp's filament will burn open. If the 60 watt 220 volt lamp is used on a 110 volt supply, the lamp will glow at half brightness, but it will last for a very long time before the filament burns open.
If it is a 12 volt panel it will light a 12 volt bulb. Most likely it is not a 12 volt panel, it is some other voltage, so you then need equipment like an inverter to convert the energy to 12-volt energy.
To determine how many 12-volt, 50-watt bulbs can be used on a 100 VA transformer, first convert the transformer's capacity from VA to watts, which is effectively the same for resistive loads (100 watts in this case). Each 50-watt bulb requires 50 watts, so you can divide the total available watts by the wattage of one bulb: 100 watts ÷ 50 watts/bulb = 2 bulbs. Therefore, you can use 2 of the 12-volt, 50-watt bulbs on a 100 VA transformer.
A volt is the unit of electric potential, an amp is the unit of electric current, and a watt is the unit of power. The relationship between them is described by the equation: Power (in watts) = Voltage (in volts) x Current (in amps).
An inverter changes a d.c. input to an a.c. output. Inverter is a device to change low volt DC to high volt AC 12 Dc to 220 Ac volt So many type of inverter of watts 500 watt 1000 watt 5000 watt
A watt is the product of amperage times voltage.
Ampire. watt/volt
Probably about 180 watts, assuming 90% efficiency.
no , it will burn out
yes the bulb will actually last longer

Volt-amp is a unit of apparent power, which is the combination of voltage and current in an electrical circuit. Watt, on the other hand, is a unit of real power, which is the actual power consumed by a device. The relationship between volt-amp and watt is that watt is the product of volt-amp and power factor, which represents the efficiency of the electrical system. In simple terms, watt is the actual power used by a device, while volt-amp is the total power flowing through the circuit.
Yes
no.
