Answer 1

Answer:

Explanation:

The given combination is parallel combination.

The current flowing in the circuit is 3 Amperes.

We know that:-

$\sf{V = IR}$

Where V is voltage

Where R is resistance

Where I is current.

So, applying the resistance formula, it will be

1/R = 1/20 + 1/10

1/R = 1+2/20

R = 20/3 ohm

Now, we will find the voltage.

V = 3×20/3

V = 20 volts.

Now, current flowing in parallel combination is different, so we need to find the current separately.

20 = I × 10

I = 2 Ampere in case of 10 ohm resistance.

20 = I × 20

I = 1 Ampere in case of 20 ohm resistance.

Hence, these are the answers.

Answer 2

Explanation:

Explanation:

The given combination is parallel combination.

The current flowing in the circuit is 3 Amperes.

We know that:-

\sf{V = IR}V=IR

Where V is voltage

Where R is resistance

Where I is current.

So, applying the resistance formula, it will be

1/R = 1/20 + 1/10

1/R = 1+2/20

R = 20/3 ohm

Now, we will find the voltage.

V = 3×20/3

V = 20 volts.

Now, current flowing in parallel combination is different, so we need to find the current separately.

20 = I × 10

I = 2 Ampere in case of 10 ohm resistance.

20 = I × 20

I = 1 Ampere in case of 20 ohm resistance
