when we talk of total resistance in a circuit, is internal resistance also counted? can a circuit have both parallel and series connections?

no ohms law is valid for //lel & series connections
internal resistance is the inner hinderance caused to current by a
battry..

Yes, a circuit (other than trivial ones) often have both series and parallel connections. Ohms law doesn't apply to all electronic components but if you are talking about traditional resistors, it does hold. To find the overall resistance just break the circuit into parallel and series branches collapsing them until you end up with a trivial circuit.

OHM's law never changes. you should count internal resistance.
You can ahve both parallel resistance, and series connections.
Remember resistance in parallel connections the values become less. 100 ohms + 100 ohms in parallel becomes
50 ohms.

NO , in a DC circuit , but in an AC circuit you must account for reactive components such as inductance and capacitance. If you are talking about internal resistance of a battery it is not normaly counted, unless you have a specific need to. Other wise if it is to high you need a new battery if it is not then you have a good / correct battery.

Everyone would need to change the law of ones country , the law that doesn't suits one! So, there're so many laws to be changed by different individuals! I'm particularly a person to chang my country's law about 'secularism'. I want secular state in TRUE sense---unfortunately I don't get that. Rather if I write in favor of my idea, I get threatening mails from unknown! :-(

YA ohms law has different apps. in both series and parallel. .. . . if v talk of Series ( R=R1+R2+R3....Rn) and parallel (1/R=1/R1+1/R2+...1/Rn) ... i think this'll explain tat the resistance can change in both connections .... however the law remains the same .... a circuit san hav both series and parallel .... hope it helps
