Circuits

Mains supply provides alternative current while battery provides direct current.

the 4 colour resistor colour code is thus:

black = 0

brown = 1

red = 2

orange = 3

yellow =4

green = 5

blue = 6

violet = 7

grey = 8

white = 9

the first two numbers are found directly on the table.

the third number is not the number, but the number of zeros at the end.

therefore the value is yellow = 4, green = 5, and brown equals 1 zero, so the total is 450 ohms.

the gold band indicates tolerance. gold is by far the most common, and indicates a tolerance of +/- 5%. therefore the actual value of the resistor could be anywhere between 427.5 and 472.5.

It is my understanding that the 80286 has a 16-bit data bus. This was a doubling of the original 8086/8088 processors.

1. You need a power source

2. You need a load. Anything from a single resistor to a whole network of resistors.

3. You need wiring to connect the power source to the load or loads.

An electric circuit connected so that current passes through each circuit element in turn without branching.

That's a matter of opinion. Here's mine:

The most important component of an electric circuit is the power supply.

Because without it, no other component of the circuit does anything.

There are two types of circuits: series, and parallel. In a series circuit, electricity flows through all components of the circuit in a series. This means it flows from the power source, through all the components as a whole, then back to the source. A parallel circuit, on the other hand has the electricity flow through the components separately. Power flows from the source to each individual component individually, then back to the source. In a series circuit, if one component is missing or broken, the circuit will not function. With a parallel circuit, on the other hand, if a part is missing, or broken, all the other components will still work.

There is no such thing as the "purity of electrons". A heat sink is used to keep a device reasonably cold.

Which component is designed to remove high-voltage spikes and surges from a power line so that they do not damage a computer system?

-- The voltage across every circuit element is the same, and is equal to the power supply voltage.

-- The current through each circuit element is in inverse proportion to its impedance.

-- The sum of the currents through all circuit elements is equal to the power supply current.

Who was first is unknown, but both Ewald Georg von Kleist and Pieter van Musschenbroek are credited with inventing the Leyden Jar in 1745. This electrical storage device was the first opportunity to use electricity to create a useful electric circuit. There is no acceptable and convincing record of what the first circuits were and who created them. But, credit for the first true electric circuit is due to these two men.

The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.

Any circuit that includes a switch (or other control - or measuring indicator) is a series circuit.

A cold circuit

A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.

Practically all electrical devices include integrated circuits today. Anything from a domestic electric kettle to a space station will include them

If resistance is decreased, the current will increase according to Ohm's Law. This is because current is directly proportional to voltage and inversely proportional to resistance. Lower resistance allows more current to flow for a given voltage.

You haven't listed ANY components that are considered loads. I would submit, though, that a resistor ... or anything else that actually dissipates energy, no matter what you may call it ... is the only component that can be a 'load'. Inductors and capacitors are not, unless they also have some resistance, and then it's the resistance that comprises the load. As in so many other aspects of real life, dissipation is the key.

While it is possible that the company producing the capacitor is using the NF as an identification tool, usually we would expect nF to specify the capacitance or value of the capacitor. For example, a capacitor with the value of 10nF ought to have a capacitance of about 10 nano Farads. This is equivalent to 10*10-9 Farads.

The flasher relay in a circuit serves to control the blinking of turn signals or hazard lights in vehicles. It functions by intermittently opening and closing the circuit, allowing electricity to flow to the lights in a timed sequence. This creates the characteristic flashing effect, enhancing visibility and signaling intentions to other drivers. Additionally, it helps prevent constant power draw by cycling the lights on and off.
