Question

U1=110В I1=4A I2=8A Найти U2

Answer 1

U2=11B вот вроде так если неправильно сорян

Answer 2

To find U2, we can use the formula for power:

P1 = P2

Where P1 is the power at input (U1 * I1) and P2 is the power at output (U2 * I2).

Given: U1 = 110V (voltage at input) I1 = 4A (current at input) I2 = 8A (current at output)

We can rearrange the formula to solve for U2:

P1 = P2

(U1 * I1) = (U2 * I2)

Substituting the given values:

(110V * 4A) = (U2 * 8A)

440V = 8A * U2

Dividing both sides by 8A:

440V / 8A = U2

55V = U2

Therefore, U2 is equal to 55 volts.
