Question

Two circuits, one series and one parallel are made of two
resistors of resistance 2Ω and 3Ω, across a 9V battery.
In which combination and in which resistor is the
magnetic field the maximum?
a. Series, 2Ω
b. Series, 3Ω
c. Parallel, 2Ω
d. Parallel, 3Ω​

Answer 1

Answer:

V=6V

R

1

=2ohms

R

2

=3ohms

(a) Resistors are connected in parallel.

(b) p.d. across each resistor is same and is equal to 6V.

(c) 2 ohms resistance have bigger share of current because of its lower resistance.

(d) Effective resistance = R

1/R=1/2+1/3

1/R=5/6

R=1.2ohms

(e) Current flowing through battery ,

I=
