When a single phase supply connect to a electric heater short circuit not there why?

The electric heater is basically a resistor, designed to have the right resistance to draw the required current.
So a 2 kW heater designed for a 230 v supply is really a resistor of 28.8 ohms, so when it's connected the current is 8 amps and the power is 2 kW.

How are series parallel circuits different?
A series is an electric circuit with a single path.A parallel circuit is an electric circuit with multiple paths.
How are series circuit and parallel circuits?
For parallel circuit, there's bronchus which mean the electric current'd have to choose which path to go. There's a main loop and more than one bronchus.If the bulb in one of the bronchus break down,the other bulbs would still light up. For series circuit,there's only one path for the electric current to flow through.If one of the bulb breaks down,the other'd go out as well. The electric current of evbery bulb in a series circuit is the same while the electric current of bulb in parallel circuit are not the same. The sum of the bronchus in a parallel circuit is equal to the main loop's.The more bulbs in a path,the more resistance will there be and less brighter it will be.A larger current will flow through the path with lower resistance so te brightness of the bulb of the bronchus will hace differences asc well.
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
Can a 240 volt single phase load connect between the high leg and regular phase leg of delta connected three phase system?
yes but voltage will be out a little.This ok for something like a heater which wont care.But for an electric motor starting and overheating maybe a problem.In the US this would be 220v single phase and 208 volts 3 phase.
What are the advantages and disadvantages of a series circuit?
The main advantage to wiring a circuit with multiple accessories and access points into a series is that one main switch can control them all. This can allow a single circuit breaker, fuse, or the operator to disable them all in one step.
How are series parallel circuits different?
A series is an electric circuit with a single path.A parallel circuit is an electric circuit with multiple paths.
What is a single path for electric current to flow through?
is called an electrical circuit
Is it possible to connect two tube lights with a single choke and also you need the circuit to connect the tube lights?
yes
Explain overloading in an electric circuit?
Excessive current can be in the connection of many devices into a single socket.this may cause overload in the circuit
Why does your electric water heater make a clicking noise?
If it is a single click, from time to time, it is the thermostat cycling on and off, and it is normal.

What do you call materials that let electricity flow though?
Conductors are what the electrons flow through, in a single electric current called a circuit. Hence circuit breakers on conductors.

How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
The maximum number of duplex outlets that can be served by a single 15 ampere 120V circuit is?
10 outlets as defined by the national electric code
