Question

Three resistors each of 10 ohms
Four cells each of 3 V​

Answer 1

Answer:

0.4A

Explanation:

V = IR

I = V/R

SO, There are 4 cells of 3 V each

Total V = 4*3=12 V

Resistors are in series

And R = 10 +10+10 = 30 ohm.

I = 12/30 = 0.4A

Answer 2

Answer:

You might be knowing that current divides in only in parallel circuit.

So, here simply take out the total resistance and find out the current by ohm's law.

Total Resistance= R1+R2+R3= 10Ω+10Ω+10Ω=30Ω

Using ohm's law,

V=IR where V=voltage, I= current, R=resistance

Total voltage, 3×4= 12V

I=V/R

I= 12/30= 0.4A

Hope it helps you.
