Question

Draw a circuit diagram of an electric circuit containing a cell, a key , an ammeter ,
a resistor of 4Ω in series with a combination of two resistors (8Ω each) in parallel
and a voltmeter across parallel combination. Each of them dissipate maximum
energy and can withstand a maximum power of 16W without melting. Find the
maximum current that can flow through the three resistors.

Answer 1

ammeter should be connected in series
voltmeter should be connected in parallel
