Precautions to be taken before the circuit is switched on. If a bar magnet is broken at the middle in two parts each part is found to be a magnet. Answer: Access all questions and answers of ICSE Class 7 Physics. Circuit in series-The circuit which connects the components one after the other so that current is same through out the circuit.Circuit in parallel - The circuit where components are divided into two or more than two branches ,so that current is different in each branch, but voltage is same, is known as parallel circuit.Relation between potential difference and current is given by Ohm's Law - " It states that the current flowing through a conductor at constant temperature is directly proportional to the potential difference across the conductor. Name a domestic device in which an electromagnet is used.
