Answer:
Given: V=12V, Resistance of A=4Ω, Resistance of B=6Ω, Internal battery resistance =2Ω
(i) Total Resistance =4+6+2=12Ω
I (current in circuit)=
Totalresistance
e.m.f.
=
12
12
=1amp
(ii) Voltage drop Ir=1×2=2volt
Terminal Voltage = emf - Voltage drop
=12−2=10 volts
(iii) Potential difference across 6Ω=IR
=1×6=6V
(iv) Energy spent =I
