Question

the current in the 16 ohm resistance of the circuit is 20 A find current in 4 ohm resistance also calculate power consumed by 8 ohm resistance​

Answer 1

Answer:

5 A;10A

Explanation:

Answer 2

Given:

Current = 20A

Resistance = 16 ohm

To Find:

Current in 4 ohm resistance

Power consumed by 8 ohm resistance

Solution:

We know the formula V = I*R

For the first case, where I=20A and R =16 ohm:

V = 20*16 = 320V

Next,

When V = 320 and R = 4 ohm (given)

The current is V/R = I = 320/4 = 80A

The formula for power consumed is P = I^2 *R

I = 80A and R = 8 ohm

Thus, P = 6400 *8  = 51200Watt
