Assertion: The resistors are connected in parallel then resistance in the circuit is to be decreased Reason: On connecting the resistors in parallel, the potential difference across a resistor is proportional to its resistance. Choose the correct option (a) both a and r are true and r is the correct explanation of a (b) both a and r are true and r is not the correct explanation of a (c) a is true but r is false (d) a is false and r is true
