Ohms calculator
Ohm’s Law Calculator Voltage (V) = Current (I) * Resistance (R) Power (P) = Voltage (V) * Current (I) Enter any two known values and press “Calculate” to solve for the others. Voltage (V) Volts (V) Current (I) Amps (A) Resistance (R) Ohms (Ω) Power (P) Watts (W)
How Capacitor works
In the previous post, we discussed about the basic theory behind the capacitor. In this post, we will understand “ How capacitor works ”. As we have discussed earlier, when an electric power is provided to the capacitor, the capacitor starts accumulating the electrical charge. As soon as the power goes off, it slowly discharges […]

Different Types of Proactive Approach for Obsolescence Management
There are various types of Proactive Approach to mitigate obsolescence. The selection of suitable approach must be based on the likely obsolescence. In our previous post we discussed about types of Obsolescence mitigation approach i.e Reactive and Proactive Approach in Detail. This post will move a step further and will discuss about Different Types of […]
Different Capacitor Types in Market with Description – Part II
In the previous post, we learnt about different capacitor types available in market. Here are some more type of capacitors which you should know about.
Flywheel as Energy Storage Device, Calculations and Rotor Requirements
Flywheel as energy storage device is an age old concept. Calculation of energy storage in Flywheel and its rotor requirement are discussed.
Damped Oscillation
The process of producing damped oscillation of Gyro and its various phases are as follows: By adding an additional weight to the lower part of the Gyro sphere, We can provide it the pendulum effect. This is done by placing a damper (with two pots, one at each end of the damper) partially filled with […]
Wee Megger
Wee-Megger is one of a kind of self-contained-high-generator and is very useful for finding an equipment’s insulation as well as its large resistive value. As the current generated by a battery driven test equipment is very low, it is highly difficult and less accurate to find a large resistance with that. To correctly measure it, […]
Signal transmission
As mentioned in my earlier posts, the i/p instructions are fed to i/p unit. To know about it in details, refer https://electricalfundablog.com/blog/instrumentation-control/process-control . Now, lets discuss about how Signal transmission happens to CPU. During the commencement of an instruction cycle, the Central Processing Unit collects each and every i/p instructions from the i/p unit and […]
Capacitor charging and discharging cycle
In our previous posts, we discussed about the basic theory and working of capacitor. In this post, we will understand about “ Capacitor charging and discharging cycle ”. Capacitor charging and discharging cycle provides a better understanding of a capacitor function. Lets take an example of a capacitor circuit in which there is no resistor/resistance. […]
