You may have heard the terms physical and logical circuits in the textbook and discussions. How do these circuits differ?

Answer #1

Physical circuit :

There are numerous physical ways circuits with the 0,1 property of binary numbers can be constructed: a magnet has a north and a south pole, a switch is either open or closed. The circuits could use electricity, fluids, light, or possibly even biological circuits at the atomic level.

Logical circuit:-

logic circuit is a circuit that executes a processing or controlling function in a computer. This circuit implements logical operations on information to process it.Logic circuits utilise two values for a given physical quantity (voltage, for example) to denote the Boolean values true and false or 1 and 0 respectively.

We can deduce the main difference from the basic definition of both the circuit. Logic circuit just defines the logic of Operations which is being carried out , but physical circuit is circuit or we can say placement of circuit elements which will carry out the logical operation.

Logic circuits use logic gates as their fundamental elements , whereas physical circuit use circuit elements like transistors , resistors etc. as their fundamental elements.

You may have heard that fish is good brain food. This is true; fish contain the kinds of fatty acids that are the right length and level of saturation for use in the cell membranes of nerve cells. When you eat fish, your body can take the fatty acids in the fish and use them for your brain cell membranes, without needing to chemically modify their leng th or level of saturation. When you eat sources of food other than...

You have three circuits that include a power supply and one (or two) lightbulbs. The only variation among these circuits involves the number of lightbulbs and how the lightbulbs are wired (if there are more than one). Circuit 1: one lightbulb; Circuit 2: two lightbulbs in series; Circuit 3: two lightbulbs in parallel. Which circuit has the greatest current? a) 1 b) 2 c) 3 d) all have the same current.
