1. A resistor has a resistance of 176 ohms. How many of these resistors should be connected in parallel so that
their combination draws a current of 5 amperes from a 220 volt supply line ?
. An electric heater which is connected to a 220 V supply line has two resistance coils A and B of 24
resistance each. These coils can be used separately (one at a time), in series or in parallel. Calculate the
current drawn when :
(a) only one coil A is used.
(b) coils A and B are used in series.
(c) coils A and B are used in parallel.
In the circuit diagram given below five resistances of 10 2,40 2,30 2,20 22 and 60 are connected a
shown to a 12 V battery.
