Q1) (a)

State Ohm’s law and Kirchhoff’s Laws in context with DC circuits.

Ohm’s Law Statement
“Current flowing through the conductor is directly proportional to the potential difference applied to the conductor, provided that no change in temperature”.
 
Kirchhoff’s Current Law Statement
“The total current or charge entering a junction is exactly equal to the charge leaving the junction as it has no other place to go except to leave, as no charge is lost within the junction “.
 
Kirchhoff’s Voltage Law Statement
“In any closed loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop” which is also equal to zero.” “In other words, the algebraic sum of all voltages within the loop must be equal to zero”.
