The values of current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below:

I (amperes): 0.5, 1.0, 2.0, 3.0, 4.0

V (volts): 1.6, 3.4, 6.7, 10.2, 13.2

Plot a graph between V and I plotted by using the given data is shown below:

Why is parallel arrangement used in domestic wiring?

What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series?

A hot plate of an electric oven connected to a 220 V line has two resistance coils A and B, each of 24resistance, which may be used separately, in series or in parallel. What are the currents in the three cases?
