Power Dissipation and Energy Absorption

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 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 the surge pro

What is RMS (Root Mean Square)?

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 is calculated Significance of  RMS value .  RMS value  of an AC vo
