1.What will be the ammeter reading in the circuit diagram given below? 

2.Explain an experiment conducted by Class 10 students at Jakar Higher Secondary School to investigate the relationship between current and potential difference. The students obtained the following graph from their experiment.

Assignment 2 

Mr. Dorji used an electric heater with a resistance of 5Ω connected to an electric source. If it produces 180 J of heat in one second, find the potential difference across the heater. 

Assignment 3 

The figure below shows a graph plotted for two distinct wires, A and B. Considering the characteristics of the graph, which wire follows Ohm’s law? Also, what are the conditions that must remain constant to verify Ohm's law?

Assignment 4 

The figure below shows a type of transformer. Assuming that the transformer has an efficiency  of 100%, calculate the supply voltage. 

Assignment 5 : There are two questions. Copy each question and then write your answers in your notebook.

1. Based on the data given in the table below, which are the ohmic conductors?

2. In the figure below, a flat rectangular coil is positioned between the poles of a magnet. The coil rotates in a specific direction due to the presence of an electric current. What modification would cause the coil to rotate in the opposite direction?
