Pooja is writing some statements but she confused to know whether the statements are correct or not? If you know the answer to this question, then tell her:

The current is directly proportional to the potential difference applied across the ends of a conductor it means that if the potential difference across the ends of a conductor is doubled, the current flowing through it also gets doubled, and if the potential difference is halved the current also gets halved.

Consider the following statements and choose the incorrect one:

We know that a thick wire has a greater area of cross section; whereas a thin wire has a smaller area of cross section. This means that a thick wire has less resistance and a thin wire has more resistance.

Keshav appeared in class test but he confused to know the incorrect statement. Would you help him to know that?

If we take a lot of copper metal 1 metre long and 1 square metre in area of cross section then its resistance will be 1.69 x 10 to the power -8.

Read the following sentences carefully, and choose the incorrect one:

Nichrome does not undergo oxidation or burn easily even at high temperature. Due to this nichrome wire can be kept red hot without burning or breaking in air.

Consider the following statements and choose the correct one:

Here, all these statements are correct. Hence, your answer will be option [D].

The commercial unit of energy is:

Kilowatt-hour is the commercial unit of electrical energy.

How much energy does a 100 W electric bulb transfer in 1 minute?

Energy transferred, E = power x time = 100 W x 60 s = 6000 J

One coulomb charge is equivalent to the charge contained in:

Since the charge of an electron is 1.6×10−19C, 6.25 × 10 to the power 18 electrons taken together constitute (6.25 × 10 to the power 18 × 1.6 × 10−19 C) or 1 coulomb of charge.

In a quiz competition, you are asked a question where you have to choose the statement which is/ are incorrect?

[A]. In series circuit, the appliances get the same voltage as that of the power supply line.

[B]. In series circuit, all the electrical appliances have only one switch due to which they cannot be turned on or off separately.

[C]. In series circuit, if one electrical appliance stops working due to some defect, then all other appliances also stop working.

[D]. In the series connection of electrical appliances, the overall resistance of the circuit increases too much due to which the current from the power supply is low.

What is meant by an electric circuit?

A continuous and closed path of an electric current is called an electric circuit.

What is fuse wire and how does it work?

The fuse is placed in series with the device. It consists of a piece of wire made of a metal or an alloy of appropriate melting point, for example aluminium, copper, iron, lead etc. If a current larger than the specified value flows through the circuit, the temperature of the fuse wire increases. This melts the fuse wire and breaks the circuit.

What do you know about a resistor?

A conductor having some appreciable resistance is called a resistor.

What is variable resistance or rheostat?

A component used to regulate current without changing the voltage source is called variable resistance.
