An Electric Kettle is Rated 3 Kw, 250 V. Give Reason Whether this Kettle Can Be Used in a Circuit Which Contains a 13 a Fuse. - Physics

An electric kettle is rated 3 kW, 250 V. Give reason whether this kettle can be used in a circuit which contains a 13 A fuse.

संख्यात्मक

We know that,

P=VI

I = `"P"/"V" = (3 xx 1000)/250` = 12A

Thus, it can be used in a circuit which contains a 13A fuse.

अध्याय 4 Current Electricity
Exercise 4.2 i | Q 6 | पृष्ठ १८७

Define electric current. What is the SI unit of electric current.

If the amount of electric charge passing through a conductor in 10 minutes is 300 C, the current flowing is:

(a) 30 A
(b) 0.3 A
(c) 0.5 A
(d) 5 A

The p.d. across a 3 Ω resistor is 6 V. The current flowing in the resistor will be:

(a) `1/2A`
(b) 1 A
(c) 2 A
(d) 6 A

In the network shown in the following adjacent Figure, calculate the equivalent resistance between the points.

Tell the odd one out. Give a proper explanation.

The diagram shows two ways of connecting three lamps P, Q and R to A.C. supply of 220 V.

Study the following circuit and find out:
(i) Current in 12 Ω resistor.
(ii) The difference in the readings of A₁ and A₂, if any.

How is direction of current related to the direction of flow of electrons?

State the conditions for the flow of charge in a circuit from one point to the other.
