Answer:
(a) 9.0 V (b) 1.5 V (c) 6.0 V
Explanation:
Here we use the simple concept of Kirchhoff's voltage law that potential in series will be added and potential in parallel will be same always. By this concept we answer all 3 parts of this question.
(a) When six 1.5 V batteries are is series means their potential is added.
So, Voltage across six batteries is
So, Net voltage is 9.0 Volts.
(b)When six 1.5 V batteries are in parallel then the net voltage across them will be voltage of either battery.
So, Voltage is
Net voltage is 1.5 Volts.
(c) Now 3 are in series and 3 are in parallel,
the Net voltage of parallel is 1.5 V , now it behaves like <u>four </u>1.5 V are in series so the net voltage become
Net voltage is 6.0 Volts.
