Question

При перемещении ползунка реостата приборы показывают U = 36 В, 24 В,12 В. I = 1,8 А, 1,2 А, 0,6 А. Вычислить сопротивление для каждого случая. Помогите у нас дистанция и я не могу решить!!!

Answer 1

Ответ:

во всех случаях будет 20 Ом

Объяснение:

R=U/I

R=36:1,8=20 Ом

R=24:1,2=20 Ом

R=12:0,6=20 Ом

Answer 2

Calculating Resistance for Different Cases

To calculate the resistance for each case, we can use the formula R = U / I, where R is the resistance, U is the voltage, and I is the current.

1. Case 1: U = 36 V, I = 1.8 A - Using the formula R = U / I, we can calculate the resistance for this case: - R = 36 V / 1.8 A = 20 Ω.

2. Case 2: U = 24 V, I = 1.2 A - Using the formula R = U / I, we can calculate the resistance for this case: - R = 24 V / 1.2 A = 20 Ω.

3. Case 3: U = 12 V, I = 0.6 A - Using the formula R = U / I, we can calculate the resistance for this case: - R = 12 V / 0.6 A = 20 Ω.

In all three cases, the calculated resistance is 20 Ω.
