What is the different between domestic and industrial electricity supply?
Electricity for industries are supplied with high voltage.Domestic supply is with low voltage.
What current is taken by a heater with a resistance of 24 ohms when connected to 120 volt supply?
I don’t know
Will the improvement of power factor will increase the efficiency?
Efficiency is defined as the ratio between the output power and the input power of a machine, expressed as a per unit or percentage. Power factor improvement has absolutely no effect on the behaviour of a load. All it does is to reduce the magnitude of the load current. A reduction in load current means that less copper can be used in the supply of energy to the load. However, it doesn't effect either the output or input power of the load. So the answer is no, power factor has no effect on the efficiency of a load. You could argue, however, that if improving the power factor of a load reduces the supply current, leading to lower line losses, then there is an improvement in the efficiency of the supply system.
If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
What is the voltage power current and resistance of an electrical heater?
The two most important ratings for an electrical heater are its rated power and its rated voltage, and these will be printed on a 'nameplate' fixed somewhere on the heater (e.g. '3 kW at 230 V').For the heater to operate at its rated power, it must be subject to its rated voltage. In the above example, the heater will only operate at 3 kW if it is supplied with 230 V.If you know the heater's power (P) and its voltage (U), then you can calculate the rated current (I) it will draw from the supply, using the equation: I = P/U.You can also determine its resistance (R), using the equation R = U2/P.
You want to fit a heater in a outhouse from a domestic 240v supply the cable has a resestance of 1.5 ohms and the heater has a resistance of 28.5 ohms what is the voltage drop in the cable?
31.5
What is Green supply chain?

What voltage does and electric water heater use?
A standard domestic water heater in a house, apartment, etc will need 220 Volts AC. They have two heating elements upper and lower and each is 110 VAC hence the 220 Volt supply. Make sure it has a dedicated circuit and a disconnect on the wall above and beside water heater.
What is the normal operating temperature of water in a domestic automatic dishwasher?
An in home dishwasher is normally connected directly to the hot water supply. The water temperature set on the hot water heater will be the same as the water temperature in the dishwasher. Normal hot water heater temps are around 120 - 140 degrees dependent upon how high the hot water heater is set at.
What causes an empty water heater?
No water supply
Heater hoses on 305 engine?
The heater hoses on a 305 engine run from the intake manifold to the heater core and the heater core to the radiator. This creates a constant source of heat to supply the heater.
How instant water heater works?
Answer:An indirect water heater uses the home heating system (furnace/boiler) to supply domestic hot water on demand- without a tank. It does this by use of a separate or secondary coil or heat exchanger which is piped to the domestic water system installed in the home heating source in your home. Hence, the name Indirect.
How do i remove heater in Nissan terrano?
Begin by removing the water supply lines from your Nissan heater core. Remove the heater core retaining bolts. The heater core will come out.
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
What is a domestic electrical supply in which outlet sockets connect to the mains supply through a continuous circuit?
