Current Electricity

best handwritten notes

Dear IIT JEE Mains and Advanced hopefuls, I am sharing brief updated notes and comprehended past inquiries on the Physics subject "Current Electricity". This PDF document contains best handwritten notes on Current Electricity that will assist you with overhauling rapidly, allude to fathomed earlier year questions and help score more stamps in JEE Mains/Advanced tests. These are best handwritten notes, & best notes trusted by the toppers. These best handwritten notes are prepared by the toppers and students of some of the best coaching institutes.

A vast and most vital topic carrying highest weightage. during this article, we'll provide you with the jist of all the key concepts.

Brief Introduction of the Topic

Let us check out this terms individually (Current Electricity).

Current: it's defined because the flow of charges per unit time which may tend by the formula

i(current) = dq/dt

Where q is that the charge and t is that the time, d indicates derivative of it.

Now, there are some common questions that arise on this subject . allow us to get into them.

Which scientist introduced the concept of Current Electricity?

There were two well renowned scientists who introduced the concepts of Direct and AC .

Thomas Edison- DC

Nikola Tesla- AC

 2) What causes current to flow in metals?

 it's just the free moving electrons which is liable for the flow of current in metals.

Electricity: it's nothing but the protons and electrons.

It also can be defined because the energy resulting from the charged particles like electrons and protons.

Now allow us to check out the electrical units that play a serious role within the chapter of dynamic Electricity

i) Voltage: In dynamic Electricity , voltage is defined because the rate of change of energy per charge and is given by a formula

V(voltage) = U/q

ii) Resistance: Resistance is defined because the force that opposes charges to flow during a circuit. it's measured in Ohms.

(or)

It is defined because the ratio of voltage and current.

It is given by a formula:

 Resistance= V/i

iii)Inductance: It are often defined because the ratio between the merchandise of L*di(t) per unit time. it's measured in Henry’s. it's given by the formula:

 v= Ldi(t)/dt

iv) Capacitance: It are often defined because the ratio of current density and strength of electrical field. it's just the other of resistance. it's measured in siemens.

v) Power: the speed of change of energy that's transmitted per time and is given by a formula:

Power= du/dt =vi

Where i is that the current and v is that the voltage.
