Point out the right statements about the validity of Kirchhoff's junction rule.
Kirchoff's junction law is equivalent to ___________.
Kirchoffs law of junctions is also called the law of conservation of:
Consider the following two statements:
(A) Kirchhoff's Junction Law follows from conservation of charge.
(B) Kirchhoff's Loop Law follows from conservative nature of electric field.
Kirchoff's first law, i.e., $\sum i = 0$ at a junction, deals with the conservation of
Consider the following two statements:
1) Kirchoff's junction law follows from the conservation of charge
2) Kirchoff's loop law follows from the conservation of energy.
Which of the following is correct?
State whether given statement is True or False
The sum of all the voltage drops around a single closed loop in a circuit is zero.
Between any two points in a circuit, the sum of all .............. is the same through any pathway.
Kirchoff's voltage law and current law are respectively in accordance with the conservation of
Kirchhoff's junction law is equivalent to
If the magnitude of voltage in a circuit changes with time between zero to peak value and direction changes periodically then the voltage is called
Kirchhoff's first law at a junction is based on conservation of
For a $DC$ circuit, Kirchoff's rules yield the following equations.
$I _{3}=I _{1}+I _{2}$
$10 = 3I _{1}-2I _{2}$
$50=2I _{2}+9.6I _{3}$
What is the current $I _{2}$ (Amps)?
Kirchhoff's Loop rule is a direct consequence of law of conservation of
Kirchhoff's first and second law shows the conservation of :-
Kirchoffs 1st and 2nd laws are based on conservation of
Kirchhoff's first law ie, $\displaystyle \Sigma i=0$ at a junction is based on the law of conservation of
The Kirchhoff's first law $(\displaystyle\sum i=0)$ and second law $\left(\displaystyle \sum iR=\displaystyle\sum E\right)$, where the symbols have their usual meanings, are respectively based on
"A good absorber of a given wavelength of radiation is also a good emitter of that wavelength." This is a statement of:
