Because it supplies them with the energy necessary for their work. IC's cannot work without energy. If they could we shouldn't put batteries into mobile devices and shouldn't connect computers to the grid. Everything could work just out of thin air.

What do you mean by Vcc pin and ground pin of an IC?
these two pins are biasing pins of ICs.
How to draw NOT gate using NPN transistor?
RTL logic: NPN transistor. Emitter grounded. Input connected to base through a resistor. Vcc also connected to base through a resistor. If the input is high or open, the transistor is on. If the input is low, the transistor is off. Connect a resistor from Vcc to the collector. The collector is the ouput. You have to play around with resistor values to setup your fan-in and fan-out properties.
Why self bias is known as self?
Self biasind is called self because in this biasing, the variation due to change in temperature increases the the collector current, which hence decreases the output voltage i.e Vout=VCC-ICR and maintains the stability
What VCC stands for in electronics?
Addition:VCC, VEE, VBB are grounded voltages of a collector, emitter, and base, respectively, on a transistor.The reason this letter is doubled is to represent a voltage connected between ground and the collector(/emitter/base). Since there is no notation to identify ground (0), the corresponding letter is doubled (IEEE standard). One way to read this notation is as the 'grounded voltage of the collector/emitter/base."AnswerThe representations like Vcc ,Vbb , Vee etc are just a part a nomenclature.it is used to represent the voltage given to the nodes of the transistorin this nomenclature voltage given to the ends are denoted by the letter v for the supply voltage and 2 times the first letter of emitter collector or the base where the voltage is given
Why coefficient of performance of absorption cycle is less than compression cycle?
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
Why does vcc voltage called vcc?
I believe that Vcc stands for Voltage Common Collector. This is because the voltage is hooked up to the collector of the transistor.
Can you use the same ground to measure input and output voltage in IC?
yes u can use.... ground is the closed loop connection(it is introduced for the circuit not to be open circuit condition).....if the vcc supply is dc input
What do you mean by Vcc pin and ground pin of an IC?
these two pins are biasing pins of ICs.
Can Voltage dividers can provide only positive output voltages?
Voltage dividers can provide anything between VCC (the most positive voltage in the circuit) and VSS (the most negative voltage in the circuit). For example, if VCC =0 and VSS = -15, then the output voltage has to be negative. ========================
Why we kept VOLTAGE collector to emitter half of voltage vcc?
We bias the common emitter amplifier to have a collector-emitter voltage of one half of Vcc in order to set the operating point halfway between the two extremes.
What does Vcc stand for on a SIM card?
VCC is an electronics designation that refers to voltage from a power supply connected to the "collector" terminal of a bipolar transistor. In an NPN bipolar junction transistor, it would be +VCC, while in a PNP transistor, it would be VCC More about sim card .... https:// telecom-hyb.blogspot. com/2017/09/what-is-sim-card.html
Full form of vcc and vdd in TTL and CMOS?

What is the voltage required for 8086 microprocessor?
The supply voltage of the 8085 is 5 volts.
Why to use Vcc in electronic ct?
collector voltage wit respect to ground
What vcc stands for?
In electronics it stands for "common collector voltage" (Vcc) Online it stands for " virtual credit card" .There are many sites selling virtual cards for online purchase.
Working process of 555 timer?
Comparator 1 has a threshold input (pin 6) and a control input (pin 5). In most applications, the control input is not used, so that the control voltage equals +2/3 VCC. Output of this comparator is applied to set (S) input of the flip-flop. Whenever the threshold voltage exceeds the control voltage, comparator 1 will set the flip-flop and its output is high. Ahigh output from the flip-flop saturates the discharge transistor and discharge the capacitor connected externally to pin 7. The complementary signal out of the flip-flop goes to pin 3, the output. The output available at pin 3 is low. These conditions will prevail until comparator 2 triggers the flip-flop. Even if the voltage at the threshold input falls below 2/3 VCC,that is comparator 1 cannot cause the flip-flop to change again. It means that the comparator 1 can only force the flip-flop's output high.To change the output of flip-flop to low, the voltage at the trigger input must fall below + 1/3 Vcc. When this occurs, comparator 2 triggers the flip-flop, forcing its output low. The low output from the flip-flop turns the discharge transistor off and forces the power amplifier to output a high. These conditions will continue independent of the voltage on the trigger input. Comparator 2 can only cause the flip-flop to output low.From the above discussion it is concluded that for the having low output from the timer 555, the voltage on the threshold input must exceed the control voltage or + 2/3 VCC. They also turn the discharge transistor on. To force the output from the timer high, the voltage on the trigger input must drop below +1/3 VCC. This also turns the discharge transistor off.A voltage may be applied to the control input to change the levels at which the switching occurs. When not in use, a 0.01 nano Farad capacitor should be connected between pin 5 and ground to prevent noise coupled onto this pin from causing false triggering.Connecting the reset (pin 4) to a logic low will place a high on the output of flip-flop. The discharge transistor will go on and the power amplifier will output a low. This condition will continue until reset is taken high. This allows synchronization or resetting of the circuit's operation. When not in use, reset should be tied to +VCC.
What is voltage level of ttl?
Standard TTL (which stands for Transistor-Transistor Logic) circuits operate on a 5V power supply. The typical level for a logical "0" is between 0V and 0.8V, and the typical level for a logal "1" is somewhere between 2.2V and 5V. Typically, a value little lower than Vcc (power source voltage) is used; in case of a 5V supply, this is usually around 4.5V, but TTL devices are built to withstand full Vcc as input, just in case.
