What precaution has to be take to run a 220 V - 600 W heater safely in a 440 V line ?

A fuse wire of radius 0.1 mm can withstand a maximum current of 1 A . What is the minimum radius of a fuse wire , made of the same meatal , that should be used to run a 220 V - 100 W heater using a 220 V mains ?

What should you do to run a 220 V - 600 W appliance using a 400 V mains ?

What is be the strength of current through a heater coil if a 220 V-0.5 kWh heater is used in 220 V line ?

What is the resistance of the filament of a 220V-60 W bulb ? If the bulb is used in a 110 V line instead of 220 V line, then what amount of power it will consume ?

If the supply voltage drop from 220 V to 200 V , what would be percentage reduction in heat produced by a 220V - 1000W heater ? Neglect the change of resistance. If the change of resistance is taken into consideration would the reduction of heat produced be smaller or larger than the previously calculated value ? Explain.

Draw a household circuit having a 1200 w toaster , a 1000 W oven a 800 W heater and a 1500 W cooler . The circuit has a heavy duty wire and a 20 A circuit breaker . Will the circuit breaker trip ,if all the appliances are operted simultaneously in a 200 V supply voltage ?

What is the peak value of the voltage of a 220V ac line?

Two electric bulbs each designed to operate with a power of 500 W in a 220 V line are connected in series in a 110 V line . What will be the power generated by each bulb ?

What is meant by electrical power? The rating of a bulb is written as 220V - 100W- What is its meaning?

A 110V -550W hearter is to be used with a 220V mains. What is the minimum value of resisrance that should with the heater? Find out the power of the whole circuit in that situation.
