Question

R1, R₂, R₂ = 5 ohm, 10 ohm, 30 ohm
Battery = 12v
find
a) the current through each resistor
b) the total current in the circuit
c) the total current in the resistance​

Answer 1

Answer:

a I =V/R

= 12/5

=2.4A

I = V/R

=12/15

=0.8A

I = V/R

=12/30

=1.42A

total current = I×I ×l current

=2.4+0.8+1.42

=4.62A

Total current in resistor = 1/R +1/R +1/R

=1/5+1/15+1/30

=1/5×6+1/15×2+1/30

=3/30

1/R =1/10

R =10 ohm
