Question

Three resistors are connected as shown in fig. with an ammeter and a cell. Calculate a) effective resistance & b) reading through ammeter shown in the diagram.​

Answer 1

Answer:

To measure current, you must connect the two leads of the ammeter in the circuit so that the current flows through the ammeter. In other words, the ammeter must become a part of the circuit itself. The only way to measure the current flowing through a simple circuit is to insert your ammeter into the circuit.

Explanation:

Answer 2

Answer:

a) effective resistance = 4 ohms

b) R = V/I => 4 = 6/I => I = 6/4 = > 3/2 ( 0.15)Amperes.
