Calculation of Power Ratings To calculate the power rating of a resistor, the formula used to calculate the power can be used which is given below: Here ‘V’ denotes voltage across the resistor while ‘I’ denotes current through it. Using Ohms’ law: Substituting in the above formula, we...
It can also be measured in watts per ampere or ampere times ohms. Voltage Formula The basic formula for the voltage is shown in the below image. Voltage Formula Triangle Voltage Formula 1 (Ohm’s Law) According to Ohm’s law, voltage can be expressed as, Example 1 As shown in the belo...
kitchen stoves and automobiles are all electrical products — and that's without even thinking of the Internet, computers and cellphones. Electrical circuits are particularly practical because they work according to consistent physical rules. Ohm's Law is a relationship among voltage, current and resi...
People say electric current flows + to - (conventional current flow) but electrons flow - to +. With tube electronics it's easier to think in terms of how the electrons are really moving in order to understand them. If you connect a wire across a battery's terminals the jammed together...

Resister is a component that acts as a barrier to the current flow. It dissipates energy as heat and creates a voltage drop in the circuit. The resistance value (R) is given in terms of "Ohms", and the voltage drop can be calculated from Ohm's Law Equation. V = IR (V = voltage...
Electrostatics and Coulomb's Law Illustration of Leyden jar Even though they didn't fully understand it, ancient people knew about electricity. Thales of Miletus, a Greek philosopher known as one of the legendary Seven Wise Men, may have been the first human to study electricity, circa 600...

10 Current-based detection methods are somewhat easier to understand in terms of design , being essentially based on ohms law. True DESAT and OC-DESAT have a few more moving parts, so in the next part of our presentation we will discuss design of these DESAT systems in greater detail. 10...
