What is Power dissipation in a circuit? Any resistor in a  circuit  that has a voltage drop across it dissipates electrical  power . This electrical  power  is converted into heat energy hence all resistors have a  power rating. This is the maximum  power  that can be  dissipated  from the resistor without it burning out. How to calculate power dissipation First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 Ω. Then, we can use the  power  rule ( P = I × V ), to find the  power dissipated  by the resistor. What is Power energy absorption? Occurring with  absorption  of  energ y or heat- absorbing . Antonyms:  energy -releasing

Clamping voltage Clamping voltage  refers to the maximum amount of voltage  that can pass a surge protector or electrical breaker before it restricts further  voltage  from passing to a device or computer. It is a process through which a device or equipment is protected from electrical surges. Clamping voltage techniques are implemented in most modern electrical and computing devices that rely on a constant electrical current to operate. Clamping voltage primarily enables a computer or any electronic device to receive voltage that is not higher than its baseline. The maximum voltage distributed to homes and offices ranges from 120 volts to 240 volts. Any device that is capable of receiving a maximum of 120 volts can crash or malfunction if it is supplied with higher voltage. Clamping voltage ensures that the computer's or device's input voltage supply remains within the baseline. Any electrical surge that is greater than the baseline is earthed by th...

RMS (Root Mean Square) What is the full form of RMS? In a direct current (DC) circuit, voltage or current is simple to define, but in an alternating current (AC) circuit, the definition is more complicated, and can be done in several ways.  Root-mean-square  (rms) refersto the most common mathematical method of defining the effective voltage or current of an AC wave. How to calculate RMS Then the  RMS  voltage (V RMS ) of a sinusoidal waveform is determined by multiplying the peak voltage  value  by 0.7071, which is the same as one divided by the square root of two ( 1/√2 ). RMS Value Formula The  RMS value  is the effective  value  of a varying voltage or current. It is the equivalent steady DC (constant)  value  which gives the same effect. For example, a lamp connected to a 6V  RMS  AC supply will shine with the same brightness when connected to a steady 6V DC supply. Why RMS Value...

Choosing Correct Thermistors Thermistors are temperature-sensing tools that are sintered semiconductors. The device shows small changes in temperature based on large changes in resistance. Thermistors are made from a mixture of different metals and metal oxides. After the materials are mixed, the thermistor is formed to its required shape. Shaped can be customized and coating can be added to make form bead-style thermistors. There are two types of coating that are possible for thermistors, and this includes epoxy and glass. A glass coating is for high temperature applications. The normal range of temperature is -58 through 572 degrees Fahrenheit. Epoxy coating are the counter-point of glass, so it works best with low temperature.  Despite the difference between coatings, they are used to mechanically protect the thermistor and wire connections. The coating also protects against corrosion and humidity. Base resistance is important for a thermistor's performance. The...

Thermistor A  thermistor  is a specific type of resistor that uses sensors to help regulate cold and heat. They can do more than simply regulate temperature. They are also used for voltage regulation, volume control, time delays, and circuit protection. These products are made up of ceramic and metal oxides, but it also contains circuits and wires. These resistors have many practical applications both in terms of manufacturing and personal products. Below, we will be going over some of the different uses and applications for thermistors throughout multiple industries. Microwave For those who have used a microwave, you have used a thermistor. They are used in these machines to determine and maintain internal temperature. Without the resistor in the microwave, there is a possibility of overheating in the unit. This could lead to potential fires. Circuit Protector If you have a power supply or surge protector in your home or office then ...

Common Collector Amplifier Common Collector Amplifiers produce an output voltage across its emitter load which is in-phase with the input signal The  Common Collector Amplifier  is another type of bipolar junction transistor, (BJT) configuration where the input signal is applied to the base terminal and the output signal taken from the emitter terminal. Thus the collector terminal is common to both the input and output circuits. This type of configuration is called Common Collector, (CC) because the collector terminal is effectively “grounded” or “earthed” through the power supply. In many ways the common collector configuration (CC) is the reverse of the common emitter (CE) configuration as the connected load resistor is changed from the collector terminal for R C  to the emitter terminal for R E . The common collector or grounded collector configuration is commonly used where a high impedance input source needs to be connected to a low impedance output l...
