The power circuit begins at the wall. The control circuit comes in over the cable. If you touch the power circuit, you get a shock. If you touch the wire from the cable, nothing happens. The power contains the power to give the light to the television screen. The cable tells it what picture to show. Now, if you look at your Circuit diagram, you will see where the power comes to the computer. It might say +5v or +12v or it could show and input of 110 volts and an output of +5 and +12. There probably is also a -5 and -12 somewhere. Those are your power circuits. They power the entire computer. If you look closely at your wiring diagram, a wire from that goes to every transistor in your computer. The control circuits are likely to go anywhere. They carry data. The power circuits all go back to one point. The control circuits do not.

What is the difference between PCC panel and PDB panel?
There is no difference between PCC ( Power Control Centre) and PDB (Power Distribution Board). Although they have different names, but their functions are same i.e. controlling power feeders.
What is an electrical switch that is actuated by a separate circuit?
An electrical switch that is actuated by a separate circuit is known as a relay. A relay allows a low-power circuit to control a high-power circuit without direct electrical connection between the two. When the separate circuit activates the relay's coil, it creates a magnetic field that closes or opens the contacts in the high-power circuit, enabling or disabling the flow of electricity. This setup is commonly used in automation, control systems, and protection devices.
Why there is a need of rectification?
Most countries in the world use AC or Alternating Current, most circuits these days use DC or Direct Current. To control a modern circuit with mains power means putting a control circuit containing a rectifier between the power source and the whatis being controlled. The rectifier changes AC power into DC power.
What is difference between mcc and pcc panels?
MCC panel is the bunch of motor feeders from where you can control power to connected motors, that's why it is called Motor Control Centre. PCC ( Power control centre), comprises of HT breaker's which controls power to transformers/ MCC's/ HT motors.
How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
Why isolation is needed between power circuit and control circuit?
Isolation between power and control circuits is necessary to prevent high voltages or currents from affecting sensitive control components, ensuring safety and reliability of the control system. It also helps in preventing electromagnetic interference and noise from the power circuit, which could disrupt the control signals and lead to system malfunctions.
What is the difference between power and authority?
Power is the ability to control, while authority is the right to enforce control.
What are three sources of power for control circuit?
Three sources of power for control circuits are batteries, power supplies, and solar panels. These sources provide the necessary voltage and current to operate control devices and components in a circuit.
Which part of the circuit supplies the potential difference in the circuit?
The power source, typically a battery or a generator, supplies the potential difference in the circuit. This potential difference allows charges to flow through the circuit and power the electrical components.
What determines the voltage in an electrical circuit?
The voltage in an electrical circuit is determined by the difference in electric potential between two points in the circuit. It is measured in volts and is influenced by factors such as the power source, resistance in the circuit, and the components connected to it.
How does electricity move through a circuit?
Electricity moves through a circuit by flowing from the power source, such as a battery or outlet, through the wires and components in the circuit, and back to the power source. This flow of electricity is driven by the voltage difference between the positive and negative terminals of the power source.
What supplies energy to move elecricity through a circuit?
In a circuit, the energy needed to move electricity is provided by a power source such as a battery or a generator. This power source creates a voltage difference between the circuit's components, which pushes the electric charges to flow through the circuit.
What is the difference between PCC panel and PDB panel?
There is no difference between PCC ( Power Control Centre) and PDB (Power Distribution Board). Although they have different names, but their functions are same i.e. controlling power feeders.
What is the relationship between EMF and potential difference in an electrical circuit?
The relationship between EMF (electromotive force) and potential difference in an electrical circuit is that EMF is the total energy supplied by a source, while potential difference is the energy transferred per unit charge as it moves through the circuit. In simpler terms, EMF is the total push provided by the power source, while potential difference is the push experienced by the charges as they flow through the circuit.
What is the difference between mcc and pcc?
MCC-Motor control center which consist of motor staters to control the motor. PCC-power contol center which is control the power to distribution system

When one electrical circuit controls another electrical circuit through relay the first circuit is called?
When one electrical circuit controls another circuit through a relay, the first circuit is called the "control circuit." The control circuit operates the relay, which in turn switches the second circuit, known as the "load circuit," on or off. This allows for the control of high-power devices using a low-power signal.
