Question

The total resistance in this circuit is

Answer 1

Let us solve for it

Explanation:

In the given figure we need to find the total resistance and total voltage .

We know that :

• In series total R =R1 +R2 ...
• In parallel total R formula is : 1/R=1/R1 +1/R2.....

• We also know ohm's formula is : V=IR

So, in this circuit : R1=12 ohm

R2=8 ohm

R3=10 ohm

Ammeter reading = 10A

so, they are in series therefore ,

Total R = R1 + R2 +R3

R=12 +10+8=30 ohm

To find voltage we have : V=IR

                                          V =10 x 30=300Volts
