3.1.1. Revisit to pre-requisite topics

Try these first

1. 1.

   Define Kirchhoff's Current Law.

   Hint

   Remember the phrase 'In equals Out.'

2. 2.

   What does Kirchhoff's Voltage Law state?

   Hint

   Think about how voltage drops in a loop.

3. 3.

   What does Kirchhoff's Current Law (KCL) state?

   • The sum of voltages in a loop is zero
   • The sum of currents entering a node equals the sum leaving
   • Power is conserved in circuits

   Hint

   It relates currents at a junction.

4. 4.

   True or False: Thevenin's theorem only applies to DC circuits.

   • True
   • False

   Hint

   Consider the applications of Thevenin's theorem.

5. 5.

   Consider a circuit where two currents enter a junction (I1 = 3A, I2 = 4A). What is the current leaving that junction?

   Hint

   Use KCL to solve for the outgoing current.

6. 6.

   You have a circuit with two resistors in series and a voltage source of 10V. Calculate the voltage drop across each resistor if they are equal.

   Hint

   Apply KVL around the loop.
