Question

U=5B R=0,5 Ом P=? решение

Answer 1

P=U²/R=5²/0.5=50 Вт
=====================

Answer 2

Дано: U = 5В
R = 0.5Ом
Найти: Р - ?
Решение: P = UI ; I - ?
I= U÷R ; I = 5÷0.5=10A
P=5×10=50
Ответ: Р = 50Вт

Answer 3

To find the power (P) in a circuit, we can use the formula:

P = U^2 / R

where: U = Voltage (in volts) R = Resistance (in ohms) P = Power (in watts)

Given that U = 5 volts and R = 0.5 ohms, we can now calculate the power (P):

P = (5)^2 / 0.5 P = 25 / 0.5 P = 50 watts

So, the power in the circuit is 50 watts.
