#### Measuring the resistance of a component – different ways

In this post, we are going to discuss different ways of measuring the resistance of a component. Resistance is defined as R = V/I. This obviously gives ways of measuring ...

#### How to find resistance using Resistor Colour Codes

Small resistors use coloured or painted bands which represent their resistive value and tolerance. These coloured painted bands produce a system of identification generally known as a Resistors Colour Code ...

#### How does alternating current differ from direct current?

In this post, we will find out the answer to a very common question: "How does alternating current differ from direct current?" Direct current implies that the current flows in ...

#### Ammeters and Voltmeters – FAQs, connection, concepts

Ammeters measure the current of a circuit, and voltmeters measure the voltage drop across a resistor. Ammeters and voltmeters are cleverly designed because it is important in the design to ...

#### Capacitors & Capacitance – Formula & other FAQs

Capacitors are components of electrical circuits that temporarily store electric charge. Capacitors are simple passive devices. The capacitor is a component that has the ability or "capacity" to store energy ...

#### [pdf notes] Electric Circuits Grade 10 & Grade 11 Notes download | class 10 & class 11 physics notes on Electric Circuits

This Electric Circuits Notes [PDF download] is primarily for the 10th & 11th grade physics syllabus of different international boards. This also covers the class 10 and class 11 physics ...

#### Potential dividers – how does it work? – explain with examples

Sometimes we want to use only part of the e.m.f. of a supply. To do this, we use an arrangement of resistors called a potential divider circuit. In other words, ...

#### What is the Internal Resistance of cells?

What is the Internal Resistance of cells & how it affects the current flow in a circuit? All electric cells are made of materials that have resistance. The resistance of ...

#### How to define Voltages, Electromotive Force (emf), and Potential Difference (PD)?

Voltages, Electromotive Force (emf), and Potential Difference (PD) - These 3 terms are often used while we discuss electrical circuits. Hence exactly knowledge about these certainly helps us to understand ...

#### Symbols & functions of Common components of electrical circuits – How to get?

The following tables describe some of the common components of electrical circuits, their functions, images, and the symbols that are used to represent them in circuit diagrams. Figure 1 Figure ...

#### Voltages in series circuits and parallel circuits – easy understanding

Voltages in series circuits and parallel circuits - Let's see how total voltage in series circuits and parallel circuits are calculated. Voltages in series circuits A series circuit has no ...

#### How current flows through series and parallel circuits? A quick reference

Here we will see how current flows through series and parallel circuits. Currents in series circuits In a series circuit, devices are connected so there is only one closed path ...

#### Equivalent resistance of a parallel circuit with derivation & numerical problems

The equivalent resistance of a parallel circuit is found using Kirchoff's junction rule, which states that the sum of the currents entering a branch (or junction) must be equal to ...

#### Series Circuits, Resistors in series & equivalent resistance – numerical

What is a series circuit? A series circuit consists of several resistors connected in sequence, one after the other. This increases the length of the conductor. Therefore total resistance increases ...
