Question

Connect three resistors R1, R2and R3 of 4 Ohm each in parallel across the battery of 16V. Also connect ammeter and voltmeter in the circuit. Find :-
a)Total resistance of the circuit.
b)Total current flowing through the circuit.
c)Current flowing through resistor R1.
d)Energy and power used by R2 resistor in 10 seconds.

Answer 1

Answer:

(a). R1=R2=R3=4 ohm

1/Rs=1/R1+1/R2+1/R3

=1/4+1/4+1/4

1/Rs=3/4

Rs=4/3

(b). I=V/R

=16/4/3

=4×3/1

=12 A

(c). I=V/R1

=16/4

=4 A

(d). P=VI

=16×4

=64 Jule/sec.

E=PT

=64×10

=640 J
