12: Explain Kirchhoff's laws in detail. |
| Answer» <p>Kirchhoff’s Current Law (KCL): This is also known as the first law, point rule or junction rule and is the principle of conservation of electric charge. It states that the amount of current flowing into a node or junction is equal to the sum of the currents flowing out of it. This is used in conjunction with Ohm’s law in performing nodal analysis.</p><p>Kirchhoff’s Voltage Law (KVL): This is also known as the second law, loop rule or mesh rule and is based on the principle of conservation of energy. It states that the sum of the voltages or electrical potential differences in a closed network is zero. The total amount of energy gained must equal the amount of energy lost per unit charge.</p> <p>Kirchhoff'scurrentlaw(1stLaw)statesthat current flowing into a node (or a junction) must be equal to current flowing out of it. This is a consequence of charge conservation.Kirchhoff'svoltagelaw(2ndLaw)statesthat the sum of all voltages around any closed loop in a circuit must equal zero.</p> <p>Kirchhoff'scurrentlaw(1stLaw)statesthat current flowing into a node (or a junction) must be equal to current flowing out of it.

1.What do you mean by rotation of earth? |
| Answer» <p>By definition, the Earth’s rotation is the amount of time that it takes to rotate once on its axis. This is, apparently, accomplished once a day – i.e. every 24 hours. However, there are actually two different kinds of rotation that need to be considered here. For one, there’s the amount of time it take for the Earth to turn once on its axis so that it returns to the same orientation compared to the rest of the Universe. Then there’s how long it takes for the Earth to turn so that the Sun returns to the same spot in the sky.</p> | |
