Questions + Answers key
Take MCQ Science Test1.
Name any two appliances which work under the principle of heating effect of current.
2.
On what factor does the resistance of a wire depend at a particular temperature?
3.
State Ohm’s law.
4.
The values of current I flowing through a resistor for various potential differences V across the resistor are given below. What is the value of resistor?
| I (ampere) | 0.5 | 1.0 | 2.0 | 3.0 | 4.0 |
| V (volt) | 1.6 | 3.4 | 6.7 | 10.2 | 13.2 |
[Hint: plot V-I graph and take slope]
5.
Calculate the amount of charge that would flow in 2 hours through an element of an electric bulb drawing a current of 2.5A.
1.
The appliances which work under the principle of to after, heating effects are iron box, water heater, toaster etc.
2.
The resistance offered by a material at a particular temperature depends on the,
(i) geometry of the material and
(ii) nature of the material.
3.
Ohm's law states that electric potential difference across two points in an electrical circuit is directly proportional to the current passing through it that is
V ∝ I
The proportionality constant is the resistance (R) offered between two points. Hence Ohms law is written as
V = RI (or) V = IR
4.
5.
Time(t) = 2 hours
= 2 x 60 x 60 = 7200 sec
Current flowing (I) = 2.5 A
Amount of charge (Q) = ?
I = Q / t
Q = It
= 2.5A x 7200 sec = 18000 C
