In this post, we will discuss different factors that affect the capacitance of a parallel-plate capacitor. The greater the capacitance of a capacitor the greater the charge held by it ...

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 ...

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 ...

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 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 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 ...

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 ...

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? | Define the internal resistance of a cell All electric cells are made of materials that have resistance. The resistance of the cell is called ...

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 ...

Figure 1 below presents 17 circuit symbols for a variety of circuit components like cell, battery, switch open, switch closed, ammeter, voltmeter, motor, resistor, thermistor, fuse, diode, LED (Light Emitting ...

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 ...

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 ...

In this post, we will study a simple parallel circuit. Then we will derive the equivalent resistance formula in a parallel circuit. Using this formula, we will solve numerical problems ...

In this post, we will study simple series circuits with the help of a series circuit diagram. We will also go through related topics like resistance in series or resistors ...
