Ten $60 \, W, 220 \, V$ bulbs are connected in series to a $220 \, V$ supply. The power consumed in the circuit is ......... $W$.

If in the circuit shown below,the internal resistance of the battery is $1.5 \, \Omega$ and $V_P$ and $V_Q$ are the potentials at $P$ and $Q$ respectively,what is the potential difference between the points $P$ and $Q$?

Assertion: In a simple battery circuit,the point of the lowest potential is the positive terminal of the battery.
Reason: The current flows towards the point of the higher potential,as it does in such a circuit from the negative to the positive terminal.

Two bulbs rated $(25\, W - 220\, V)$ and $(100\, W - 220\, V)$ are connected in series to a $440\, V$ line. Which one is likely to fuse?

Two $220\; V, 100\; W$ bulbs are connected first in series and then in parallel. Each time the combination is connected to a $220\; V\; AC$ supply line. The power drawn by the combination in each case respectively will be

An ammeter with a zero error is connected in series with a silver voltameter. The ammeter reads $0.54 \ A$. In $1 \ hour$, $2.0124 \ g$ of silver is deposited. If the electrochemical equivalent of silver is $1.118 \times 10^{-3} \ g \ C^{-1}$, then the error in the ammeter reading is ............... $A$.
