When a high resistance voltmeter is connected directly across an electric bulb, its reading is 2 V. An electric
cell is sending the current of 0.4 ampere (measured by an ammeter) in the electric circuit.
a. Draw the circuit.
b. Find the resistance of the electric bulb,
c. State the law that is applied for making these calculation. If a graph is plotted between V and I, show the
nature of the graph obtained.
