All bulbs are identical in the circuits shown. An ammeter is connected next to the battery, as shown. Rank the current readings in the ammeter, from greatest to least.
Solution 3R Step 1 of 3: The bulb in the given circuit bulb can be taken as resistor because when electricity is passed through the resistor, the electrical energy is converted into other form of energy such as heat or light. Similarly when the electricity is forced to pass through the bulb(tungsten), which is a resistor, the energy is converted into light and heat.
