How can you measure the ampere or watt for power supply?
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
How many amps is in 750mA?
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 750 amps equals 180,000 watts. One horse power is 746 watts.
What type of power does a power supply convert to?
A power supply is generally only converting the mains voltage down to a lower voltage suitable for low voltage equipment. It turns 120 v into 18v or 12v or 5v or any other voltage it is specified for. In most countries outside US, we have 220 volt AC in the mains. Power is however power. One could say that Voltage is the speed of which the power run. A power supply generally slows down the speed of electricity. Regards.
How many vA equal to 1watt?
In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
60 amps is how many watts?
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 40 amps equals 9600 watts. One horse power is 746 watts.
What tool can you use to troubleshoot power supply issues measure current resistance or voltage?
multimeter
How do you find open circuit voltage in circuit?
"Open circuit voltage" is a characteristic of a battery or power supply. You measure it exactly as the term suggests ... disconnect any load from it (or open the ON/OFF switch), and measure the voltage across the terminals of the battery or power supply while it's not supplying current to anything.
Explain the power supply circuit for conductivity electrode?
You have to excite it with a sinusoidal signal then measure the current or voltage
Can the power supply provide a negative voltage output?
Yes. Depending on the design, the power supply can provide any voltage desired.
When do you need to convert the voltage for appliances?
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
Which voltages are supported by a Toshiba power supply?
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
How can you measure the power or voltage of a potato clock?
A voltmeter would measure the voltage. If you measure the voltage drop over a known low resistance you get a kinda-sorta idea of the power available.
Two technicians are discussing how to measure the voltage outputs of a power supply. Technician A says that the power supply must be connected to the system and turned on before voltage can be measu?
It does have to be turned on. A highly regulated PS will be the same under load as without a load. But it may not be able to supply the amps. Best connect it and test it. WHO WON?

What is vsb in power supply?
Voltage Standby
What to do if the power supply is too low?
Obtain a power supply that has the correct output voltage that you need.
