Question

Calculate
A. total resistance
B. Total current
C. Current through 3 ohm resistor
and battery is of 12v

Answer 1

Answer:

I = V/r

12/3 = 4A

R =I Multiple V

4 multiple 12

=48

Explanation:

Hence, Total R =48

Total I = 4A

Maybe it's wrong...

I am not sure

I am sorry......

Answer 2

A) Total resistance-

In series- R = R1 + R2 + R3 ...

In parallel 1/R = 1/R1 + 1/R2 + 1/ R3 ...

B) Total current - according to ohms law V = IR

from this

total current (I) = VOLTAGE/RESISTANCE

C) Current through 3 ohm resistor and battery of 12 volt -- V = I R

=> V/R = I

=> 12/3 = I

=>I = 4 ampere

--Ampere is the SI unit of current. It is named after a scientist.

--Ohm is unit of resistance.
