Suresh arranges the electric circuit shown below to measure the current flowing through and the potential difference of a bulb.

Is the circuit correct? If not, then identify the mistake.

Observe the circuit shown below. All the three switches are open.

Identify the switch/switches that on being closed will cause the fuse to blow.

Three bulbs are connected in a circuit in an identical way. When a fourth bulb is also connected to the same circuit in the same way, brightness is reduced then the bulbs are connected in _____.

Choose the correct statement:

When the same current $\left(i\right)$ flows through two circuits as shown in the figures, then (assume that all bulbs are identical)

(i) 

(ii) 

(A) Bulbs in the first combination glow with more brightness.

(B) Bulbs in the second combination glow with more brightness.

In an electrical circuit three incandescent bulbs $A$, $B$ and $C$ of rating $40 \mathrm{W}, 60 \mathrm{W}$ and $100 \mathrm{W}$ respectively are connected in parallel to an electric source. Which of the following is likely to happen regarding their brightness?
