What is the resistance of an electric arc lamb when hot, if the lamp uses `20 A` when connected to a `200` volt line ?

An electric lamp of 100Omega , a toaster of resistance 50Omega , and a water filter of resistance 500Omega are connected in parallel to a 200V source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances, and what is the current through it?

An electric lamb of 100 Omega , a toaster of resistance 50 Omega and a water filter of resistance 500 Omega are connected in parallel to a 220 V source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances ans what is the current through it ?

A lamp has a resistance of 96 ohms. How much current flows through the lamp when it is connected to 120 volts?

An electric lamp of 200 ohm and a toaster of 100 ohm are connected in parallel to a 220 V electricity source. What will be resistance of an electric iron which when connected to the same electric source permits the same current as the total current flowing through both the appliances described above?

The two bulbs as in the above question are connected in series to a 200 volt line. Then

An electric lamb of 100 Omega a toaster of resistance 50 Omega and a water filter of resistance 500 Omega are connected in parallal to a 220 V source.What is the resistance of the electric iron connected to the same cource that takes as much current as all the three application and what is the current through it?

A resistor of 4 ohm resistance and an electric lamp of 20 ohm resistance are connected in series across a 6 volt battery. Draw a lebelled circuit diagram by using the symbols for ohm and volt. Calculate: (a) total resistance of the circuit. (b) current flowing through the circuit. (c) potential difference across the resistor. (d) potential difference across the electric lamp.

A 75 W lamp is designed to be used on 15 V. What is its resistance? If the lamp is to be used on 120 V, what resistance must be connected in series with it?
