In a circuit, two resistors of resistances 5 Omega and 10 Omega are connected in series. Compare the current passing through the two resistors.

Obtain an expression for equivalent resistance of two resistors connected in a series combination.

(a) Three resistors 2 Omega, 4 Omega and 5 Omega are combined in series. What is the total resistance of the combination ? (b) If the combination is connected to a battery of emf 20 V and negligible internal resistance, determine the current through each resistor, and the total current drawn from the battery.

If two resistors of 25 Omega and 15 Omega are joined together in series and then placed in parallel with a 40 Omega resistor, the effective resistance of the combination is:
