A hot plate of an electric oven connected to a 220V line has two resistance coils A and B, each of `24Omega` resistance, which may be used separately, in series, or in parallel. What are the currents in the three case?
Amount of current when the coils are used separately.

Two resistances 99 ohms and 1 ohm are connected in parallel. Find the current in each when the main current in the circuit is 10 ampere.

Several electric bulbs designed to be used on a 220V electric supply line, are rated 10 W. How many lamps can be connected in parallel with each other across the two wires of 220V line if the maximum allowable current is 5A?

Two resistances each of value 2 ohm and 4 ohm are connected in parallel and the total current through the combination is 1 amp. What are the values of current through each resistance?

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?

Two 6 ohm resistances are connected in parallel and a 12 V battery is connected across the combination. Find the current flowing through each of the resistances.

Two lamps, one rated 100W at 220V, and the other 60w and 220V, are connected in parallel to electric mains supply. What current is drawn from the line if the supply voltage is 220V?
