What else can I help you with?
What 3 things do you need for an electric current?
To have an electric current, you need a source of voltage (such as a battery or power supply), a complete electrical circuit (includes wires and components), and a conductive material (such as copper wire) for electrons to flow through.
What 3 things must be present to make an electromagnet?
To make an electromagnet, you need a power source (such as a battery), a conductive wire or coil, and a ferromagnetic core (such as iron). When an electric current flows through the wire, a magnetic field is created in the core, turning it into a magnet.
What are 3 ways to induce an electric current in a wire?
You can induce an electric current in a wire by moving a magnet near the wire, passing a current through a nearby wire, or changing the magnetic field around the wire.
What are the 3 types of eletricity?
The three types of electricity are static electricity, current electricity (also known as electric current), and alternating current (AC) electricity. Static electricity refers to the build-up of electric charge on the surface of objects. Current electricity is the flow of electric charge through a conductor, while alternating current (AC) electricity is a type of current where the flow periodically reverses direction.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.

What has the author Jeff Keljik written?
Jeff Keljik has written: 'Electricity 4' -- subject(s): Alternating current, Alternating current Electric motors, Electric controllers, Electric generators, Electric motors, Alternating current 'Electricity 3'
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What are the 3 electric hobs?
The three (electric) things (hobs) that you put your pans on when cooking.

What is starting current for a 6.7kw 3 phase electric motor?
One need to know the voltage, the power factor and starting torque, to derive the starting current. The information provided in the question is not sufficient.

What are the 3 properties of metal?
They are lustrous and malleable They conduct heat They conduct electric current
What are the 3 metallic properties?
They are lustrous and malleable They conduct heat They conduct electric current
How many things are needed to have current?
3 things Volts, ohms, and amps

If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
