Figure A and B, show a bulb connected to a cell in two different ways.
$(i)$. What will be the direction of the current through the bulb in both the cases $(Q\ to\ P\ or\ P\ to\ Q)$?
$(ii)$. Will the bulb glow in both cases?
$(iii)$. Does the brightness of the glowing bulb depend on the direction of current through it?"
$(i)$. In a circuit, current always flows from the positive terminal to the battery's negative terminal. So, in the first case, the current will flow from Q to P and in the second case, the current will flow from P to Q.
$(ii)$. In both cases, the current is flowing. So, the bulb will glow in both cases.
$(iii)$. No, the bulb's brightness does not depend on the direction of the current flowing through it. The brightness of the bulb depends on the amount of current and voltage.
