Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?

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?

When a certain weight is suspended to a long uniform wire its length increases by one cm. If the same weight is suspended to another wire of the same material and length but having a diameter half of the first one, the increase in its length will be

A wire of given material having length I and area of cross-section A has a resistance of 8Omega . What would be the resistance of another wire of the same material having length l/2 and area of cross-section 4A?

It is easier to catch, a table tennis ball than a cricket ball even when both are moving with same velocity. Why?

Two resistances of 5 ohm and 10 ohm are connected in parallel and then a current is passed through them from a battery of 6 volt. Calculate the currents drawn from the battery and also the currents flowing through each of the resistances.

Why is ice at 273 K more effective in cooling than water at the same temperature?
