Not very easily. A clamp on amp meter has to go around only one of the circuit conductors. If the clamp on meter is used around the power cord the two wires in the cord have a cancellation effect and the meter will read zero. If you can separate the load's wires that plug into the cord and clamp around that wire you will get a load amperage reading.

Why UPS is not charging on Inverter?
UPS (UNINTERUPTED POWER SUPPLY ) Its charg only AC current (Alternating current). and inverter provide current DC TO AC ( Direct current to Alternating current)
Why use AC to measure ionic conductance and why not dc current?
in order to avoid electrolysis
What is the var meter?
A VAR Meter is used to measure Reactive Power in AC Circuits - Pure reactive components dissipate zero power, which makes sense in a DC circuit, as a capacitor passes no DC current and an inductor displaces no voltage. Yet, in an AC circuit, the reactive components "seem" to dissipate power, as current passes through the capacitor and the inductor sees a voltage drop. This counterfeit power is called "reactive power" and is measured not in Watts, but in VARs (Volt-Amps-Reactive). Its mathematical formula symbol is "Q".

Give note on ac and dc voltages?
one note on Dc, and AC voltages? sure A DC is a Direct current, which means more accuracy and power. The device using DC power will maintain its action for longer with more accuracy. Whilst AC is commonly used for lights and other unimportant devices. That's the first note i could come up with. ------------------------ DC is direct current which as the name implies, the electrons (of the current) flow in ONE direction. AC is alternating current, which as the name implies, the current alternates and has a "useable/definable" frequency. AC has no definite terminal (Positive or negative) as the direction of the current always changes. This frequent switching can be seen as a sine wave.
What is a rectifier assembly?
A "Rectifier" is an electrical component that changes AC current to DC current by blocking current in one direction. High power rectifiers may be "assembled" from multiple individual component rectifiers to handle higher power or larger voltages.
What type of power cord does a sony dash have?
It is an AC plug that converts the household current to DC 9.5volts at 2.5 amps.
Why the power cord be called in different place?
in north america it calls power supply cord,in europe it calls ac power cord
What IS AC power and DC power?
AC Power is Alternating Current whereas DC Power is Direct Current.
What is the AC power cord for the psp?
console and outlet
Explain differancnce between instrument current transformer and measuring current transformer?
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
What is important when measuring power?
To measure power, you need the Voltage, and Current. In the case of AC you need the number of phases, and the power factor. Once you have these, you can find the proper formula.
Which retailers sell AC Power Cord C2G?
There are a number of retailers that sell AC Power Cord C2G. There are many available to purchase on Amazon for around $5. One can also buy them from eBay and Best Buy.
Does implantable defibrillator use ac or dc current?
DC, unless you run an extension cord.
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
Is home elect ac currant?
DC current is not used in home wiring. It may be used to power a door bell, alarm system, under counter lights, etc, that uses a transformer powered by AC that converts the power to DC. Other than that homes are wired for AC current only.
What is AC power plug?
an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
