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

What does an electric circuit mean?

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combinations would be -

An electric lamp 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,and what is the current through it?

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

How is a voltmeter connected in the circuit to measure the potential difference between two points?
