Answer» e of combination:The image given in the question is attached below.The resistors given in the circuit is parallel combination. So, this is a parallel resistor.When the resistors are connected in parallel combination, then the reciprocal of equivalent resistor is equal to sum of reciprocal of INDIVIDUAL resistors.(b) CURRENT flowing through the circuit:(i) 10 ohm resistor:On substituting the values, we get,(ii) 15 ohm resistor:On substituting the values, we get,(c) Reading in ammeter:The resistors are in parallel, so, the current flowing through the resistors are DIFFERENT. So, we need to find the sum of current flowing through the individual resistors.On substituting the values, we get,(d) SI unit of current:Current is measured with the unit Ampere. |
