Three resistors 10 Omega , 20 Omega and 31 Omega are connected in series combination. When this series combination is connected to 12V supply, by neglecting the value of internal resistance, obtain potential difference across each resistor

Three resistors 10 Omega , 20 Omega and 30 Omega are connected in series combination. Find equivalent resistance of series combination.

A set of three coils having resistances 10 Omega , 12 Omega and 15 Omega are connected in parallel. This combination is connected in series with series combination of three coils of the same resistances. Calculate the total resistance and current through the circuit, if a battery of emf 4.1 Volt is used for drawing current.

Answer the following. If the resistors 30 Omega , 40 Omega and 60 Omega are connected in parallel to a battery of 15 V. then find the effective resistance of circuit, the total current and current in each resistor .
