## Explain AC generator with the help of diagram.

-Added by Himanshi Verma Science » Electricity

priyanshu kumar

AC generator is a device which converts mechanical energy into alternating form of electrical energy. It works on the principle of electromagnetic induction. When a closed coil is rotated in a uniform magnetic field with its axis perpendicular to the magnetic field, the magnetic field lines passing through the coil change and an induced emf is produced causing the flow of current in it.

## What is Ohm's Law? and verify ohm's law.

Asked on :16 October 2019:07:45:17 PM

## What is Ohm's Law? and verify ohm's law.

-Added by Himanshi Verma Science » Electricity

priyanshu kumar

Ohm's law states that under constant temperature, the current passing through conductor is directly proportional to potential difference applied across it.

i.e., V = IR

Where,  V = potential difference R = Resistance (constant) I = Current

Ohm's law can be verified using following circuit diagram,

## Will the current flow more easily through  a thick wire or a thin wire of the same material, when connected to the same source? why?

Asked on :07 October 2019:10:54:51 AM

## Will the current flow more easily through  a thick wire or a thin wire of the same material, when connected to the same source? why?

-Added by Himanshi Verma Physics » Electricity

Himanshi Verma

The current flow more easily through a thick wire as compared to thin wire of the same material, when connected to the same source. It is due to the reason that resistance increases with decrease in thickness.

## What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series?

Asked on :07 October 2019:10:40:12 AM

## What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series?

-Added by Himanshi Verma Physics » Electricity

Himanshi Verma

Advantages of connecting electrical devices in parallel with the battery are as follows:

1) Voltage across each connecting electrical device is same and device take current as per its resistance.

2) Separate on/off switches can be applied across each device.

3) Total resistance in parallel circuit decreases, hence a great current may be drawn from cell.

4) If one electrical device is damaged, then other devices continue  to work properly.
