If current flows through two lamps arranged:
(a) in series,
(b) in parallel,
and the filament of one lamps breaks, what happens to the other lamp? Explain your answer.

The current flowing through a lamp marked as 50 W and 250 V is

The current flowing through a lamp marked as 50 W and 250 V is

The current flowing through a lamp , marked as 60 W and 240 V is

A current of 0.4 A flows through a lamp, when a P.D. of 230 V is applied to it. Find the power of the lamp.

A student made an electric circuit shown here to measure the current through two lamps. (a) Are the lamps in series or parallel? (b) The student has made a mistake in this circuit. What is the mistake? , (c) Draw a circuit diagram to show the correct way to connect the circuit. Use the proper circuit symbols in your diagram.

In the given circuit, A, B, C and D are four lamps connected with a battery of 60V. Analyse the circuit to answer the following questions (i) What kind of combination are the lamps arranged in (series or parallel)? (ii) Explain with reference to your above answer, what are the advantages (any two) of this combination of lamps? (iii) Explain with proper calculations which lamp glows the brightest? (iv) Find out the total resistance of the circuit.

The current through a lamp decreases by 1% what is the percentage change in power of the lamp ?

If the current through a flood lamp is 5A, what charge passes in 10 seconds?

In a domestic electric supply, if two bulbs are connected in series instead of parallel, what will happen if the filament of one of the bulbs breaks?
