Question
Fig. $A$ and $B$, show a bulb connected to a cell in two different ways.
  1. What will be the direction of the current through the bulb in both the cases. $(Q$ to $P$ or $P$ to $Q)$
  2. Will the bulb glow in both the cases?
  3. Does the brightness of the glowing bulb depend on the direction of current through it?
✓

Answer

  1. The direction of current will be from $0$ to $P$ in $A$ and direction of current will be from $P$ to $Q$ in $B$. This is because the direction of current is always from positive terminal to negative terminal of the cell or battery. This is the conventional direction of flow of current in the circuit.
  2. Yes, the bulb will glow in both the cases because for the bulb to glow, we just need to complete the circuit.
  3. No, the brightness of the bulb never depends upon the direction of current passing through it.
