Draw a schematic diagram of a circuit consisting of a battery of
three cells of 1.5V each, a plug key, a 4Ω resistor, a 6Ω resistor
and an 8Ω resistor all connected in parallel. Connect an ammeter
to measure the current across the 8Ω resistor and a voltmeter
across all three resistors to measure the voltage, what would be
the readings of the ammeter and voltmeter?
