A 6V battery is connected to a bulb of resistance of 12 ohms. Find the current through the bulb

Three identical lamps each having a resistance R are connected to the battery of emf as shown in the figure. Suddenly the switch S is closed. (a) Calculate the current in the circuit when S is open and closed (b) What happens to the intensities of the bulbs A,B and C. (c ) Calculate the voltage across the three bulbs when S is open and closed (d) Calculate the power delivered to the circuit when S is opened and closed (e ) Does the power delivered to the circuit decreases, increases or remain same?

Draw the symbols for battery, open switch, bulb, and resistor.

Figure shows an inductor L and a resistor R connected in parallel to a battery through a switch. The resistance R is the same as that of the coil L. Two identical bulbs are put in each arm of the circuit? (i) Which of the bulb lights up earlier when switch S is closed? (ii) Will the bulbs be equally bright after some time?
