We can bring change in current and voltage in a circuit by connecting the resistors in different ways.
a) What are the different ways that we can connect resistors in a circuit?
b) What will be the least resistance that you can get by using 222, 452 and 622 resistors in a circuit. Draw the circuit.
c) When the above resistance are connected to 6 V battery in parallel. What will be the current through 20 resistance?
