Question: 1
How ammeter and voltmeter are prepared.
Answer: 1
1-26
Ammeter: Ammeter is an instrument which measured the current. This is made by connecting a small resistance in parallel to the coil of the galvanometer. This resistance is called the "shunt" . The major portionof the amount passed through the shun.
Question: 2
Define Potential difference.
Answer: 2
2-26
"The amount of energy supplied to one coulomb charge by a battery is called its potential difference."
Question: 3
What does a step -up transformer do.
Answer: 3
3-26
A step -up transformer increase the voltage givne b primary coil because in step-up transormer numebr of turns in secondary coil are greater in number.
Question: 4
What is electric current.
Answer: 4
4-26
"The amount of charge that passes through any cross-sectionin one second is called current."
Question: 5
Define Conventional current.
Answer: 5
5-26
The amount of positive flowing in one direction is equivalent to the same amount of change flowing in opposite direction.
Question: 6
Where is a shunt resistance connected to convert a galvanometer into ammeter.
Answer: 6
6-26
Ammeter is made by connecting a small resistance in parallel to small resistance is called the " Shut"
Question: 7
What are resistors.
Answer: 7
7-26
the conductors having large resistance are called resistors e.g. Bulb, heater, fun adn electric iron are all resistors.
Question: 8
Define Ohm's law. Write and its formula.
Answer: 8
8-26
The current flowing through a conductor is directly proportional to the potential difference provided that the tempeerature and the physical state of the conductor does not change .
Question: 9
What does step -down transormer do.
Answer: 9
9-26
A setp -down transormer decrease the voltage given by the primary coil because in step-down transormer the number of turns in secondary coil are less than primary coil.
Question: 10
Which quantities does Ohm's law relate.
Answer: 10
10-26
Ohm's law give a relationship between current and potential difference according to him.
Question: 11
Write the names of types of capacitors.
Answer: 11
11-26
1- Fixed capacitor
Question: 12
Define Resistance.
Answer: 12
12-26
"The opposition to the flow of charges is called resistance.
Question: 13
What is circuit breaker.
Answer: 13
13-26
Now a day circuit breakers are replacing the fuses. These are turned off automatically on passing more or less current than its limit.
Question: 14
Difference between A.C. and D.C. current.
Answer: 14
14-26
"The current which always flow in one direction is called the direct current.
Question: 15
Write the precuationary measured of electricity dangers.
Answer: 15
15-26
By taking these measures, dangers can be avoided to much extent.
Question: 16
Write the brief note on multi-meter.
Answer: 16
16-26
This is an instrument which can be used to measure current, potential difference and resistance. This is called AVO meter here "A" stands for Ampere, "V" for Volt and "O" for Ohm.
Question: 17
What is transformers.
Answer: 17
17-26
Transformer: Transformer is a device that decrease orincreases the A.C. voltage in A.C current doest not flow in one direction but it changes direction repeatedly.
Question: 18
Defien Switches.
Answer: 18
18-26
A switch completes or breaks a circuit when the switch is turned off, no current flows through the circuit.
Question: 19
Define Resistance. Write its formula and unit.
Answer: 19
19-26
The opposition to the flow of charges is caleld resistance. Resistance is equal to the ratio of potential difference and current. From equation
Question: 20
What is fuse
Answer: 20
20-26
Fuse is such a device, which does not allow current to pass through it over a certain limit. A fuse is introduced in the path of live wire in every parallel circuit.
Question: 21
Define Ohm
Answer: 21
21-26
"If one volt potential difference applied across the ends of a conductor gives rise to a current of one ampere, the resistanc eof the conductor is one ohms.
Question: 22
How electricity measured.
Answer: 22
22-26
If you want to know how much electricity have you consumed in a certain period follow procedure givne below.
Question: 23
Write Types of Fuse.
Answer: 23
23-26
1- A fuse used in a circuit is of slightly higher value.
Question: 24
Define Electric Shock.
Answer: 24
24-26
When a current flows through a living body , it is called an electric shock.
Question: 25
Define Ammeter.
Answer: 25
25-26
Ammeter: Ammeter is an instrument which measures the current.
Question: 26
Define Galvanometer.
Answer: 26
26-26
Galvanometer is an instrument, which detects the current. Different measiuring instruments are made by making modification in the galvanometer.
