Q:

Working of safety fuses depends upon

1. magnetic effect of the current

2. chemical effect of the current

3. magnitude of the current

4. heating effect of the current

Select the correct answer using the code given below.

 

A) 1, 2, 3 and 4 B) 1, 2 and 3 only
C) 3 and 4 only D) 4 only
 
Answer & Explanation Answer: C) 3 and 4 only

Explanation:

An electric fuse is a device which is used to limit the current in an electric circuit. The fuse safeguards the circuit and the electrical appliances from being damaged.

The fuse wire is generally an alloy of lead and tin. It has a low melting point and breaks the circuit if the current exceeds a safe value. The thickness and length of the fuse wire depends on the maximum current allowed through the circuit.

It is connected in series in the beginning of the electric circuits.

If too many electrical appliances of high power rating (like electric iron, water heater etc) are switched on at the same time, they draw an extremely large current from the circuit. This condition is called overloading and it can cause overheating of the wiring and lead to a fire. (heating effect and magnitude of the current)

Q:

Consider the following chemical reaction :

aFe2O3(s) + bCO(g) + cFe(s) + dCO2

In the balanced chemical equation of the above, which of the following will be the values of the coefficients a, b, c and d respectively?

A) 3, 2, 3, 1 B) 1, 3, 2, 3
C) 2, 3, 3, 1 D) 3, 3, 2, 1
 
Answer & Explanation Answer: B) 1, 3, 2, 3

Explanation:

Fe2O3 + 3CO = 2Fe + 3CO2

Hematite + Carbon Monoxide = Iron + Carbon Dioxide

In this reaction, the iron oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
